Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
To facilitate a clearer understanding of the various embodiments of the present application, some relevant knowledge is presented.
Unicode (Unicode) is a standard coding system for representing text characters. It defines a unique identifier for each character in the character set, called a codepoint. Unicode uses hexadecimal numbers to represent the code of each character, typically beginning with the prefix "U+" followed by a four to eight-bit hexadecimal number, e.g., the Unicode code point for Latin capital "A" is U+0041 and the Unicode code point for Chinese "o" is U+554A.
The Unicode is only responsible for assigning unique codes to characters, and the specific display effect of the characters is not related, and in practice, it may happen that one character corresponds to two different Unicode codes, and the actual display effect of the characters of the two different Unicode codes is the same, for example, the character "two" corresponds to two different Unicode codes (u+2f06 and u+4e8c), and the actual display effect of the character "two" corresponds to each of u+2f06 and u+4e8c.
User Interface (UI) based searches are typically based on visual effects. For characters having the same display effect, there is a possibility that Unicode code values of the search request and Unicode code values stored in the OFD document are not identical. In this case, a search failure is returned, which may cause a trouble in understanding. Even if the user realizes that this is due to search failure caused by inconsistency of Unicode code values, additional work is required for the ordinary user to find that the character corresponds to another Unicode code, and another Unicode code is input in the input method, which also requires additional support of the input method. In general, input methods support only one Unicode code.
In actual user searching, text searching of the OFD document usually uses Unicode code values corresponding to the text, which can cause a problem that the text cannot be searched when two different Unicode codes exist for characters of the same font, for example, assuming that a Unicode code value stored by a character 'two' in the OFD document is u+2f06, a search failure result is obtained when the user uses u+4e8c for searching.
Based on the problems, the invention provides an open format document OFD searching method, secondary searching of the OFD document can be automatically realized through the first coding value and the coding table of the target character, and the searching accuracy and efficiency of the OFD document are improved.
The open layout document OFD search method of the present invention is described below with reference to fig. 1 to 3.
FIG. 1 is one of the flow diagrams of the open format document OFD searching method provided by the invention, and as shown in FIG. 1, the method comprises steps 101-103; wherein,
step 101, obtaining a search request for target characters in an OFD document; the search request is to indicate a first encoded value of the target character.
It should be noted that, the method for searching the open format document OFD provided by the present invention is suitable for a scenario of searching the content in the OFD document, and the execution body of the method may be an open format document OFD searching device, for example, an electronic apparatus, or a control module for executing the method for searching the open format document OFD in the open format document OFD searching device.
Specifically, when a user needs to search for content in an OFD document, the user opens the OFD document by using an OFD document reader (e.g., a Fuxin reader), and triggers a search request for target characters in the OFD document reader through an input method; the search request is used to indicate a first code value of the target character, where the first code value may be a Unicode code value, for example, the target character is "two", and the first code value is "0x4E8C".
And 102, searching the OFD document based on the first coding value of the target character to obtain a first search result.
Specifically, according to a first coding value of the target character, searching the OFD document, and obtaining a first search result; the first search result is successful or failed.
Step 103, performing secondary search on the OFD document based on the first coding value and the coding table of the target character to obtain a second search result under the condition that the first search result is search failure; the encoding table includes an association relationship between the first encoding value and a second encoding value for each of a plurality of characters.
It should be noted that, for different coding modes, each character corresponds to different coding values, some characters have a one-to-one association relationship, and some characters have a one-to-many association relationship.
Fig. 2 is a schematic diagram of code values corresponding to characters in different coding modes provided by the invention, as shown in fig. 2, the display effect of the kanji characters "mu" is the same, the coding modes include GB2312, BIG5, GBK, GB18030, UTF-8, UTF-16BE, UTE-16LE and Unicode, but for different coding modes, it can BE seen that the two "mu" are different in the coding modes, whether the coding values corresponding to the coding modes are GB18030, UTF-8, UTF-16BE, UTF-16LE or Unicode codes, and from the aspect of program codes, the two completely different characters are corresponding to two different code values.
Specifically, the encoding table includes an association relationship between a first encoding value and a second encoding value of each of a plurality of characters, that is, one character corresponds to the first encoding value and the second encoding value.
Table 1 is a coding table provided by the present invention, as shown in Table 1, tab [ U1 ]]=[U2]Wherein U1 and U2 are encoded values of Unicode, e.g., tab [0x9FDA0]=0x2fd 5, i.e. 0x9FDA0 and 0x2FD5 correspond to the same character'”。

The character set composed of a plurality of characters included in the coding table is a character set of Kangxi radicals, the first coding value is a Chinese character coding value, and the second coding value is a Kangxi radical coding value. Kangxi radicals refer to a radical system used in Kangxi dictionary and comprise twenty-four radicals in total, and the radicals are arranged in Unicode ranges of [ U+2F00, U+2FDF ], but the actual ranges of the radicals are [ U+2F00, U+2FD5] because the radicals actually recorded in Kangxi dictionary are only twenty-four. Usually, the coding of the input characters by the input method is less than direct coding of Kangxi radicals, and the coding table considers the mapping from the coding of the Chinese characters of the common Chinese characters to the coding of the Kangxi radicals.
In practice, under the condition that the first search result is a search failure, according to the first coding value and the coding table of the target character, performing secondary search on the OFD document to obtain a second search result; the second search result is successful or failed, and the position information of the target character in the OFD document can be directly searched through secondary search under the condition that the second search result is successful; and under the condition that the second search result is search failure, the fact that target characters needing to be searched do not exist in the OFD document is indicated.

(2) And under the condition that the first coding value of the target character is failed to match with the third coding values of all characters corresponding to the OFD document, determining that the first search result is failed in search.
Specifically, under the condition that the first code value of the target character is failed to match with the third code value of all the characters corresponding to the OFD document, the fact that the characters which are not matched with the target character in all the characters corresponding to the OFD document are explained can determine that the first search result is failed in search.
(3) And under the condition that the first code value of the target character is successfully matched with the third code value of any character corresponding to the OFD document, determining that the first search result is successful in search.
Specifically, under the condition that the first code value of the target character is successfully matched with the third code value of any character in all characters corresponding to the OFD document, the fact that the characters matched with the target character exist in all characters corresponding to the OFD document is indicated, and the first search result can be determined to be successful in search.
