Embodiment

[0028] Embodiment: a kind of full-text search method based on block method, it is characterized in that: comprise the following steps:

[0029] (1) The establishment of the block index, when searching for the first time, when it is necessary to generate block data and block information tables, extract the text content of each file, write it into the block data file, and extract the file name, file md5 value and area The corresponding start position and end position of the file in the block data are written into the block information table, and the size of each block is calculated by the total file index data size;

[0030] (2) Update the block data, extract the md5 value corresponding to the file name in the block index, and compare it with the md5 value in the index. If there is any change, it means that the block data has changed, and the entire block needs to be updated. When the md5 values ​​corresponding to each file in the block index table are equal, it means that the f...

Abstract

The invention discloses a full-text search method based on a block method. The full-text search method comprises the following steps: (1) establishing a block index; (2) updating the block data; and (3) searching keywords. Compared with the prior art, the method has the advantages that full-text search can be performed on multiple documents more quickly, and when the number of documents containingkeywords is smaller, the search efficiency of the block method is higher due to the fact that the number of keyword comparison times is smaller during search. No matter how many documents containingkeywords are in conventional search, all the documents need to be compared, so that the search time is the same. When each document contains the search keyword, the search times of the two documents are the same, the file opening and reading times of the block method are less, the search efficiency difference between the two documents is minimum, the work flow is simple and practical, and the useis faster.

Description

technical field [0001] The invention relates to the field of computer office work, in particular to a full-text search method based on a block method. Background technique [0002] Find documents containing a certain keyword in many documents. At this time, it is necessary to perform a full-text search on multiple documents. The traditional method is to open each file to search, and return the documents containing the search keyword, such as searching 10,000 documents. It takes about 3 minutes for a regular document, and it takes 30 minutes to search 100,000 documents, so some methods are needed to solve the search speed problem. [0003] Currently, taxonomy is used to classify documents first, then determine which category the keyword is in, and then search in the corresponding category, thereby reducing the search range and shortening the search time, but only suitable for clear categories and able to judge It is available when the category of the keyword is listed. There...
