Description

Interval value retrieval method, storage medium and computer Technical Field

The present invention relates to the field of information retrieval, and more specifically, to an interval value retrieval method, a storage medium and a computer.

Background Art

Using computers or the Internet to search for data can help people quickly find the content they need in massive amounts of data, among which keyword search is a commonly used search method. In the prior art, keyword search uses a "what you see is what you get" matching logic, that is, when searching, only the text that already exists in the database can be searched, and it is determined whether the keyword entered by the user matches the text that already exists in the database. For example, if the keyword entered by the user is the number "3", the number "3" must appear clearly in the database to successfully match.

The "what you see is what you get" keyword search matching logic of the prior art cannot realize the search for the middle value of the interval value. The interval value expresses an interval segment of the value, and the middle value refers to the value between the minimum and maximum values of the interval value. For example, the interval value is 0 to 9, and the middle value is any value between 0 and 9, such as 3. According to the principle of "what you see is what you get", the interval value 0 to 9 can only express two values, 0 and 9. The prior art can only retrieve 0 and 9, and the values between 0 and 9 cannot be retrieved. For example, the keyword entered by the user is 3. Although 3 is between 0 and 9, it cannot be retrieved because 3 is not actually displayed, resulting in inaccurate search results.

DETAILED DESCRIPTION

In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

In a preferred embodiment, referring to FIG1 , the interval value retrieval method of this embodiment is applied to the retrieval field, including computer local data retrieval, server data retrieval, and cloud data retrieval, etc. An interval value refers to an interval segment of a value, that is, a value range. An interval value can be a numerical range containing only numbers, such as 0 to 9; or it can be a value range containing numerical units, such as 0°C (Celsius) to 9°C, 0m (meter) to 9m, 0A (ampere) to 9A, etc., where 0°C (Celsius), m (meter) and A (ampere) are numerical units. Specifically, the interval value retrieval method includes a process of establishing a numerical set and a numerical retrieval process, which are described separately below.

First, before searching, a value set must be established. The process of establishing the value set includes the following steps:

Step a1: Detect interval values in the document.

Specifically, the document of this embodiment refers to a file containing certain data, especially a file containing text, so that it can be used for text retrieval in this embodiment. It can be understood that there are many forms of file format expression, and this embodiment does not limit this. As a choice, the document includes but is not limited to word documents, TXT documents, PDF documents, EXCEL tables, PPT documents, web pages, etc. Interval values usually have specific expressions, which can be represented by intermediate symbols such as "-", "~", "()", "[]", etc., such as interval values 0-9, 0~9, (0,9), [0,9] represented by intermediate symbols; they can also be expressed by text representing ranges, such as 0 to 9, from 0 to 9, etc., between 0 and 9, etc. Based on the specific expressions of interval values, these specific expressions are made into interval value models, and the interval value model is used to detect interval values matching the interval value model in the document. For example, the interval value model "number-number", if the text that conforms to the interval value model "number-number" is detected in the document, it is considered that the interval value is retrieved, for example, 0-9 conforms to the interval value model "number-number". By using the interval value model, automatic detection of interval values in documents can be achieved without the need for manual search for interval values in documents, which is highly efficient and low-cost.

Step a2: Obtain a value set corresponding to the interval value according to a preset algorithm, wherein the value set includes the middle value of the interval value.

Specifically, after the interval value in the document is retrieved, the value set corresponding to the interval value is obtained according to the preset algorithm, each interval value corresponds to a value set, and the value set includes the intermediate value of the interval value. The value set includes at least one intermediate value, and the intermediate value is greater than the minimum value of the interval value and less than the maximum value of the interval value. It can be understood that the more intermediate values a value set corresponding to a certain interval value contains, the greater the probability of being retrieved, thereby increasing the probability of the interval value being retrieved. For example, the interval values are 0 to 9, and the intermediate values can be 1, 2, 3, 4, 5, 6, 7, 8, that is, the value set corresponding to the interval values 0 to 9 is composed of the intermediate values 1, 2, 3, 4, 5, 6, 7, 8. However, it should be noted that the value set does not include all values between the minimum and maximum values of the interval values, but takes as many values as possible. The more values taken, that is, the greater the density, the greater the probability of the interval value being retrieved; but the more intermediate values, the greater the corresponding data processing amount, so it is necessary to strike a balance between the number of intermediate values and the probability of being retrieved.

Step a3: Establish a first correspondence between the value set and the document.

Specifically, after obtaining the value set corresponding to a certain interval value, a first correspondence between the value set and the document is established, that is, a first correspondence between the value set and the document where the corresponding interval value is located is established. If a document contains more than two interval values, the document corresponds to multiple value sets. Usually, a computer or server or cloud database stores a large number of documents, retrieves the interval values in each document, and establishes a value set corresponding to each document, thereby establishing a value set corresponding to the database.

It can be understood that after the first correspondence is established, each middle value in the value set corresponds to the document, so that the middle value of the interval value in the document can be retrieved. It should be noted that the value set corresponding to a certain interval value in the document is newly generated data outside the document, which does not belong to the document itself and does not need to modify the document. Instead, it is stored separately as separate data, and then the first correspondence between the value set and the document is established.

Secondly, after the value set is established, the value retrieval is performed. The value retrieval process includes the following steps:

Step b1, receiving search information, the search information includes the value to be searched.

Specifically, the search information input by the user is received, and the search information includes the value to be searched, and of course, may also include other search information. It should be noted that the value to be searched is a value or a number.

Step b2: Retrieve the value to be retrieved from the value set.

Specifically, since all the intermediate values in the numerical set are already specific values, they can be searched through the "what you see is what you get" text matching method, so the value to be searched can be searched in the numerical set. For example, the interval values are 0 to 9, and the intermediate values can be 1, 2, 3, 4, 5, 6, 7, 8, that is, the numerical set corresponding to the interval values 0 to 9 is composed of the intermediate values 1, 2, 3, 4, 5, 6, 7, 8. If the value to be searched input by the user is 3, the value to be searched 3 is searched in the numerical set 1, 2, 3, 4, 5, 6, 7, 8. It can be understood that the value to be searched can still be used to search for existing content in the document, and reference can be made to the prior art, which will not be repeated here.

Step b3: If the value to be retrieved is in the value set, determine the document corresponding to the retrieval information according to the first corresponding relationship.

Specifically, by searching for the value to be searched in the value set, if the value to be searched is in the value set, the document corresponding to the search information is determined according to the first corresponding relationship, thereby realizing the search of the portion of the interval value that is not directly displayed. For example, the interval values are 0 to 9, and the middle values can be 1, 2, 3, 4, 5, 6, 7, 8, that is, the value set corresponding to the interval values 0 to 9 is composed of the middle values 1, 2, 3, 4, 5, 6, 7, 8. If the value to be searched input by the user is 3, the value 3 to be searched is searched in the value set 1, 2, 3, 4, 5, 6, 7, 8, and it happens to match, then the document corresponding to the value 3 to be searched can be determined.

In addition, if the value to be searched input by the user is 3.5, it cannot be successfully matched in the value set 1, 2, 3, 4, 5, 6, 7, 8, but 3.5 is indeed in the interval value 0 to 9. It is also explained here that this embodiment can only increase the probability of the interval value being searched to a certain extent, but cannot achieve full coverage search of the interval value. It can also be seen that the more values the value set takes, that is, the greater the density, the greater the probability of the interval value being searched.

This embodiment achieves retrieval of partial middle values of interval values by filling in partial middle values of interval values, thereby improving the accuracy of interval value retrieval.

In some embodiments of the interval value retrieval method, a numerical set corresponding to the interval value is obtained according to a preset algorithm, and the numerical set includes the intermediate value of the interval value. This embodiment provides a preset algorithm: starting from the minimum value of the interval value, the value is gradually increased according to the preset step length until the maximum value of the interval value, and each increase in the preset step length generates an intermediate value, and the numerical set corresponding to the interval value is composed of all the intermediate values. For example, if the interval value is 0 to 9 and the preset step length is 1, then it increases by 1 each time starting from 0, and the intermediate values obtained are 1, 2, 3, 4, 5, 6, 7, 8, that is, the numerical set corresponding to the interval value 0 to 9 is composed of the intermediate values 1, 2, 3, 4, 5, 6, 7, 8.

In some embodiments of the interval value retrieval method, a numerical set corresponding to the interval value is obtained according to a preset algorithm, and the numerical set includes the intermediate value of the interval value. This embodiment provides a preset algorithm: starting from the maximum value of the interval value, the value is gradually reduced according to the preset step length until the minimum value of the interval value, and each reduction of the preset step length generates an intermediate value, and the numerical set corresponding to the interval value is composed of all the intermediate values. For example, if the interval value is 0 to 9 and the preset step length is 1, then starting from 9, it is reduced by 1 each time, and the intermediate values obtained are 1, 2, 3, 4, 5, 6, 7, 8, that is, the numerical set corresponding to the interval value 0 to 9 is composed of the intermediate values 1, 2, 3, 4, 5, 6, 7, 8.

In some embodiments of the interval value search method, after step a1 and before step a2, a process of determining a preset step length is also included: obtaining the numerical unit corresponding to the interval value, the numerical unit is usually located immediately after the interval value, and the unit immediately after the interval value can be used as the numerical unit of the interval value. For example, if the interval value is 0 to 9°C, the unit ℃ immediately after the interval value 0 to 9 is used as the numerical unit of the interval value. It can be understood that the positional relationship between the interval value and the numerical unit is diverse, and the numerical unit corresponding to the interval value can be determined based on other positional relationships between the interval value and the numerical unit. The principle is similar to that of the numerical unit being located immediately after the interval value, and will not be explained one by one.

Further, after determining the numerical unit corresponding to the interval value, the preset step length corresponding to the numerical unit is searched according to the second corresponding relationship. The second corresponding relationship is the correspondence between the numerical unit and the preset step length. It can be understood that the data accuracy corresponding to each numerical unit is usually fixed. For example, the accuracy corresponding to Celsius ℃ is usually 0.1, that is, when the user searches for a numerical value, it is usually accurate to 0.1℃. At this time, the preset step length can be 0.1, and the numerical set obtained at an accuracy of 0.1 can meet the needs of most users. Therefore, the setting of the second corresponding relationship needs to be combined with the general accuracy requirements of the numerical unit in a large amount of data and the experience of the staff. Each numerical unit corresponds to a preset step length.

This embodiment determines the preset step length according to the numerical unit corresponding to the interval value, so that the value of the preset step length is more reasonable, thereby making the value of the middle value of the interval value more reasonable, thereby increasing the accuracy of interval value retrieval.

In some embodiments of the interval value retrieval method, after step a1 and before step a2, a process of determining a preset step length is also included: obtaining the numerical unit corresponding to the interval value and the product information to which the document belongs, wherein the numerical unit is usually located immediately after the interval value, and the unit immediately after the interval value can be used as the numerical unit of the interval value. For example, if the interval value is 0 to 9°C, the unit ℃ immediately after the interval value 0 to 9 is used as the numerical unit of the interval value. It can be understood that the positional relationship between the interval value and the numerical unit is diverse, and the numerical unit corresponding to the interval value can be determined based on other positional relationships between the interval value and the numerical unit. The principle is similar to that of the numerical unit being located immediately after the interval value, and will not be explained one by one.

Furthermore, the product information to which the document belongs refers to the product information of the product defined, described or attributed by the document. The product information includes but is not limited to the product name, product model, product field, product use, etc. Any information that can be used to describe the product can be used as product information. The product described by the interval value can be further clarified through product information, and the preset step length can be determined more accurately. For example, if the interval value is 0 to 9mm (millimeter), if the corresponding product information is the size of the computer, the preset step length can be 1mm; if the corresponding product information is the size of the memory stick in the computer, the preset step length can be 0.1mm.

Further, after determining the numerical unit and product information corresponding to the interval numerical value, the preset step length corresponding to the numerical unit and product information is searched according to the third corresponding relationship, and the third corresponding relationship is the corresponding relationship between the preset step length, the numerical unit and the product information. It can be understood that in this embodiment, the preset step length is determined by considering both the numerical unit and the product information. The preset step length is determined from the numerical unit itself and the object it describes, which can make the preset step length more reasonable. Therefore, the setting of the third corresponding relationship needs to be combined with the general accuracy requirements of the numerical unit in a large amount of data, and the accuracy requirements of the product information on the size and the experience of the staff. Each numerical unit and product information corresponds to a preset step length.

This embodiment determines the preset step length according to the numerical unit corresponding to the interval value and the product information. Compared with determining the preset step length only according to the numerical unit, the value of the preset step length can be more reasonable, thereby making the middle value of the interval value more reasonable, thereby increasing the accuracy of interval value retrieval.

In a preferred embodiment, referring to FIG2 , the interval value retrieval method of this embodiment is applied to the retrieval field, including computer local data retrieval, server data retrieval, and cloud data retrieval, etc. An interval value refers to an interval segment of a value, that is, a value range. An interval value can be a numerical range containing only numbers, such as 0 to 9; or it can be a value range containing numerical units, such as 0°C (degrees Celsius) to 9°C, 0m (meter) to 9m, 0A (ampere) to 9A, etc., where 0°C (degrees Celsius), m (meter) and A (ampere) are numerical units. Specifically, the interval value retrieval method includes a process of establishing a numerical set and a numerical retrieval process, which are described separately below.

First, before searching, a value set must be established. The process of establishing the value set includes the following steps:

Step a11: Detect the interval values in the document and the position information of the interval values in the document.

Specifically, the document of this embodiment refers to a file containing certain data, especially a file containing text, so that it can be used for text retrieval in this embodiment. It can be understood that there are many forms of file format expression, and this embodiment does not limit this. As a choice, the document includes but is not limited to word documents, TXT documents, PDF documents, EXCEL tables, PPT documents, web pages, etc. Interval values usually have specific expressions, which can be represented by intermediate symbols such as "-", "~", "()", "[]", etc., such as interval values 0-9, 0~9, (0,9), [0,9] represented by intermediate symbols; they can also be expressed by text representing ranges, such as 0 to 9, from 0 to 9, etc., between 0 and 9, etc. Based on the specific expressions of interval values, these specific expressions are made into interval value models, and the interval value model is used to detect interval values matching the interval value model in the document. For example, the interval value model "number-number", if the text that conforms to the interval value model "number-number" is detected in the document, it is considered that the interval value is retrieved, for example, 0-9 conforms to the interval value model "number-number". By using the interval value model, automatic detection of interval values in documents can be achieved without the need for manual search for interval values in documents, which is highly efficient and low-cost.

Furthermore, after detecting the interval value in the document, the position information of the interval value in the document is obtained, and the position information is used to locate the position of the interval value in the document. For example, if the position information is line 3 on page 2, the interval value can be located on line 3 on page 2. If the document contains multiple interval values, the position information corresponding to each interval value is obtained, and a corresponding relationship between each interval value and the position information is established.

Step a21, obtaining a value set corresponding to the interval value according to a preset algorithm, wherein the value set includes the middle value of the interval value.

Specifically, after the interval value in the document is retrieved, the value set corresponding to the interval value is obtained according to the preset algorithm, each interval value corresponds to a value set, and the value set includes the middle value of the interval value. The value set includes at least one middle value, and the middle value is greater than the minimum value of the interval value and less than the maximum value of the interval value. It can be understood that the more middle values a value set corresponding to a certain interval value contains, the greater the probability of being retrieved, thereby increasing the probability of the interval value being retrieved. For example, the interval values are 0 to 9, and the middle values can be 1, 2, 3, 4, 5, 6, 7, 8, that is, the value set corresponding to the interval values 0 to 9 is composed of the middle values 1, 2, 3, 4, 5, 6, 7, 8. However, it should be noted that the value set does not include all values between the minimum and maximum values of the interval values, but takes as many values as possible. The more values taken, that is, the greater the density, the greater the probability of the interval value being retrieved.

Step a31: establish a first corresponding relationship between the value set and the document, and a fourth corresponding relationship between the value set and the position information.

Specifically, after obtaining the value set corresponding to a certain interval value, a first correspondence between the value set and the document is established, that is, a first correspondence between the value set and the document where the corresponding interval value is located is established. If a document contains more than two interval values, the document corresponds to multiple value sets. Usually, a computer or server or cloud database stores a large number of documents, retrieves the interval values in each document, and establishes a value set corresponding to each document, thereby establishing a value set corresponding to the database.

It can be understood that after the first correspondence is established, each middle value in the value set corresponds to the document, so that the middle value of the interval value in the document can be retrieved. It should be noted that the value set corresponding to a certain interval value in the document is newly generated data outside the document, which does not belong to the document itself and does not need to modify the document. Instead, it is stored separately as separate data, and then the first correspondence between the value set and the document is established.

Furthermore, after establishing the first correspondence between the value set and the document, the document corresponding to the value set is determined according to the first correspondence. In order to enable the user to further locate the specific position of the interval value in the document, this embodiment simultaneously establishes a fourth correspondence between the value set and the position information, and the specific position of the value set in the document can be determined according to the fourth correspondence.

Secondly, after the value set is established, the value retrieval is performed. The value retrieval process includes the following steps:

Step b11: receiving search information, where the search information includes a value to be searched.

Specifically, the search information input by the user is received, and the search information includes the value to be searched, and of course, may also include other search information. It should be noted that the value to be searched is a value or a number.

Step b21, searching for the value to be searched in the value set.

Specifically, since all the intermediate values in the numerical set are already specific values, they can be searched through the "what you see is what you get" text matching method, so the value to be searched can be searched in the numerical set. For example, the interval values are 0 to 9, and the intermediate values can be 1, 2, 3, 4, 5, 6, 7, 8, that is, the numerical set corresponding to the interval values 0 to 9 is composed of the intermediate values 1, 2, 3, 4, 5, 6, 7, 8. If the value to be searched input by the user is 3, the value to be searched 3 is searched in the numerical set 1, 2, 3, 4, 5, 6, 7, 8. It can be understood that the value to be searched can still be used to search for existing content in the document, and reference can be made to the prior art, which will not be repeated here.

Step b31: If the value to be retrieved is in the value set, determine the document corresponding to the retrieval information according to the first corresponding relationship, and determine the position of the retrieval information in the document according to the fourth corresponding relationship.

Specifically, by searching for the value to be searched in the value set, if the value to be searched is in the value set, the document corresponding to the search information is determined according to the first corresponding relationship, thereby realizing the search of the portion of the interval value that is not directly displayed. For example, the interval values are 0 to 9, and the middle values can be 1, 2, 3, 4, 5, 6, 7, 8, that is, the value set corresponding to the interval values 0 to 9 is composed of the middle values 1, 2, 3, 4, 5, 6, 7, 8. If the value to be searched input by the user is 3, the value 3 to be searched is searched in the value set 1, 2, 3, 4, 5, 6, 7, 8, and it happens to match, then the document corresponding to the value 3 to be searched can be determined.

Further, after determining the document corresponding to the search information according to the first corresponding relationship, the position of the search information in the document is determined according to the fourth corresponding relationship. For example, if the position information corresponding to the interval values 0 to 9 is page 2, line 3, then the interval values 0 to 9 can be located on page 2, line 3. In other words, if the value to be searched input by the user is 3, then the value to be searched 3 is searched in the value set 1, 2, 3, 4, 5, 6, 7, 8, and it happens to match, then the document corresponding to the value to be searched 3 can be determined. Further, the position information corresponding to the interval values 0 to 9 is page 2, line 3, then the interval values 0 to 9 corresponding to the value to be searched 3 are further located on page 2, line 3 of the document.

This embodiment achieves the retrieval of the intermediate values of the interval values by filling in the intermediate values of the interval values, thereby improving the accuracy of the interval value retrieval. In addition, when searching for the interval values in the document, the position of the interval values in the document is recorded, so that the position of the interval values in the document is directly displayed in the search results, which is convenient for users to view and improves the user experience.

In a preferred embodiment, referring to FIG3 , the interval value retrieval method of this embodiment is applied to the retrieval field, including computer local data retrieval, server data retrieval, and cloud data retrieval, etc. An interval value refers to an interval segment of a value, that is, a value range. An interval value can be a numerical range containing only numbers, such as 0 to 9; or it can be a value range containing numerical units, such as 0°C (degrees Celsius) to 9°C, 0m (meter) to 9m, 0A (ampere) to 9A, etc., where 0°C (degrees Celsius), m (meter) and A (ampere) are numerical units. Specifically, the interval value retrieval method includes a process of establishing a numerical set and a numerical retrieval process, which are described separately below.

First, before searching, a value set must be established. The process of establishing the value set includes the following steps:

Step a12: Detect the interval values in the document and the numerical units corresponding to the interval values.

Specifically, the document of this embodiment refers to a file containing certain data, especially a file containing text, so that it can be used for text retrieval in this embodiment. It can be understood that there are many forms of file format expression, and this embodiment does not limit this. As a choice, the document includes but is not limited to word documents, TXT documents, PDF documents, EXCEL tables, PPT documents, web pages, etc. Interval values usually have specific expressions, which can be represented by intermediate symbols such as "-", "~", "()", "[]", etc., such as interval values 0-9, 0~9, (0,9), [0,9] represented by intermediate symbols; they can also be expressed by text representing ranges, such as 0 to 9, from 0 to 9, etc., between 0 and 9, etc. Based on the specific expressions of interval values, these specific expressions are made into interval value models, and the interval value model is used to detect interval values matching the interval value model in the document. For example, the interval value model "number-number", if the text that conforms to the interval value model "number-number" is detected in the document, it is considered that the interval value is retrieved, for example, 0-9 conforms to the interval value model "number-number". By using the interval value model, automatic detection of interval values in documents can be achieved without the need for manual search for interval values in documents, which is highly efficient and low-cost.

Furthermore, after detecting the interval value in the document, the numerical unit is usually located immediately after the interval value, and the unit immediately after the interval value can be used as the numerical unit of the interval value. For example, if the interval value is 0 to 9°C, the unit ℃ immediately after the interval value 0 to 9 is used as the numerical unit of the interval value. It can be understood that the positional relationship between the interval value and the numerical unit is diverse, and the numerical unit corresponding to the interval value can be determined according to other positional relationships between the interval value and the numerical unit. The principle is similar to that of the numerical unit being located immediately after the interval value, and will not be explained one by one.

Step a22: Obtain a numerical value set corresponding to the interval numerical value according to a preset algorithm, wherein the numerical value set includes the middle value and numerical unit of the interval numerical value.

Specifically, after the interval value in the document is retrieved, the value set corresponding to the interval value is obtained according to the preset algorithm. Each interval value corresponds to a value set, and the value set includes the intermediate value and the numerical unit of the interval value. The value set includes at least one intermediate value, and the intermediate value is greater than the minimum value of the interval value and less than the maximum value of the interval value. It can be understood that the more intermediate values a value set corresponding to a certain interval value contains, the greater the probability of being retrieved, thereby increasing the probability of the interval value being retrieved. For example, the interval value is 0 to 9°C, and the intermediate value can be 1, 2, 3, 4, 5, 6, 7, 8, that is, the value set corresponding to the interval value 0 to 9°C is composed of the intermediate values 1, 2, 3, 4, 5, 6, 7, 8 and the numerical unit ℃. However, it should be noted that the value set does not include all values between the minimum and maximum values of the interval value, but takes as many values as possible. The more values taken, that is, the greater the density, the greater the probability of the interval value being retrieved.

Step a32: Establish a first correspondence between the value set and the document.

Specifically, after obtaining the value set corresponding to a certain interval value, a first correspondence between the value set and the document is established, that is, a first correspondence between the value set and the document where the corresponding interval value is located is established. If a document contains more than two interval values, the document corresponds to multiple value sets. Usually, a computer or server or cloud database stores a large number of documents, retrieves the interval values in each document, and establishes a value set corresponding to each document, thereby establishing a value set corresponding to the database.

It can be understood that after the first correspondence is established, each middle value in the value set corresponds to the document, so that the middle value of the interval value in the document can be retrieved. It should be noted that the value set corresponding to a certain interval value in the document is newly generated data outside the document, which does not belong to the document itself and does not need to modify the document. Instead, it is stored separately as separate data, and then the first correspondence between the value set and the document is established.

Secondly, after the value set is established, the value retrieval is performed. The value retrieval process includes the following steps:

Step b12: receiving search information, where the search information includes the value to be searched and the value unit.

Specifically, the search information input by the user is received, and the search information includes the value to be searched and the value unit, and of course, other search information can also be included. It should be noted that the value to be searched is a value or a number, and the value unit is the name of the standard quantity of the measurement object in mathematics or physics. For example, the search information input by the user is 3℃, which includes the value to be searched 3 and the value unit ℃.

Step b22: Retrieve the value and value unit to be retrieved from the value set.

Specifically, since all the intermediate values in the numerical set are already specific numerical values and corresponding numerical units, they can be searched through the "what you see is what you get" text matching method, so the numerical value and numerical unit to be searched can be searched in the numerical set. For example, the interval value is 0 to 9°C, and the intermediate values can be 1, 2, 3, 4, 5, 6, 7, 8, that is, the numerical set corresponding to the interval value 0 to 9°C is composed of the intermediate values 1, 2, 3, 4, 5, 6, 7, 8 and the numerical unit ℃. If the numerical value to be searched input by the user is 3°C, the numerical value 3°C to be searched is searched in the numerical set 1, 2, 3, 4, 5, 6, 7, 8 and the numerical unit ℃. It can be understood that the numerical value to be searched can still be used for searching existing content in the document. Please refer to the existing technology and will not be repeated here.

Step b32: If the value to be retrieved and the value unit are in the same value set, determine the document corresponding to the retrieval information according to the first corresponding relationship.

Specifically, by searching for the value to be searched and the numerical unit in the numerical set, if the value to be searched and the numerical unit are in the numerical set, the document corresponding to the search information is determined according to the first corresponding relationship, thereby realizing the search of the portion of the interval value that is not directly displayed. For example, the interval value is 0 to 9°C, and the intermediate value can be 1, 2, 3, 4, 5, 6, 7, 8, that is, the numerical set corresponding to the interval value 0 to 9°C is composed of the intermediate values 1, 2, 3, 4, 5, 6, 7, 8 and the numerical unit ℃. If the value to be searched input by the user is 3°C, the value to be searched 3 and the numerical unit ℃ are searched in the numerical set 1, 2, 3, 4, 5, 6, 7, 8 and the numerical unit ℃. If they happen to match at the same time, the document corresponding to the value to be searched 3°C can be determined.

In addition, if the value to be searched input by the user is 3.5℃, it cannot be successfully matched in the value set 1, 2, 3, 4, 5, 6, 7, 8 and the numerical unit ℃, but 3.5℃ is indeed in the interval value 0 to 9. It is also explained here that this embodiment can only increase the probability of the interval value being searched to a certain extent, but cannot achieve full coverage search of the interval value. It can also be seen that the more values the value set takes, that is, the greater the density, the greater the probability of the interval value being searched.

This embodiment achieves the retrieval of some middle values of interval values by filling some middle values of interval values, and uses two parameters, namely, the value and the unit of the value, to perform the retrieval simultaneously, thereby improving the accuracy of the interval value retrieval.

In some embodiments of the interval value search method, after step b3, the following steps are further included: It can be understood that because the database includes multiple documents, each document has a corresponding value set, and one document may correspond to multiple value sets, and there may be the same intermediate value between different value sets, so the number of documents corresponding to the search information determined according to the first corresponding relationship may exceed one. If the number of documents corresponding to the search information determined according to the first corresponding relationship exceeds one, the obtained documents are sorted and displayed according to the preset sorting rules, and the preset sorting rules can refer to the prior art. In this embodiment, when multiple search results appear, they are sorted and displayed to facilitate users to view the search results.
