AI Technical Summary

Benefits of technology

This patented technology helps users quickly find relevant content from large amounts of stored documents without having to visit their computer or device again. Its technical effect lies within this new system's ability to store indices with easy access while still being efficient at processing complex queries like those used when searching through web pages.

Problems solved by technology

This patented technology allows users with little access to large amounts of data in their web pages without having to manually enter queries into servers at all times. It uses advanced techniques like keyword searching instead of just typing them down through menus.

Embodiment example

[0025] (9) Implementation example: We applied the method of the present invention to an online document help system of a software, and achieved good results. The online document help system has fewer files, more than 100 files. The offline index file after collection (first compression) is about 18KB, and after the second compression (gzip compression), it is only 7KB. The web client obtains the After indexing data, you can do offline search completely on the web client without interacting with the server at all. The average query time is milliseconds, and further subdivided, the individual query time is less than 1 millisecond, and the total time for displaying the results is also less than 1 millisecond. More than 100 milliseconds, that is, within 0.1 second, greatly improves the user experience.

Abstract

The invention discloses a small-scale index data storage method for off-line searching. The method comprises the following steps: numbering data contents according to the sequence from 0, and storing titles into an array; splitting keywords of the data contents one by one; storing the split keywords into an associative array structure one by one, wherein keys of the associative array are the keywords per se, the value of the associative array is a large binary number, if the bit n is 1, the keywords exist in the nth piece of webpage or document, and if the bit n is 0, the keywords do not exist; after finishing analyzing all contents, conducting content compression on the associative array, namely compressing the value of the associative array, and conducting first compression on the continuous same bits by adopting a stroke compression method; conducting serialization output on the associative array into character strings, and conducting recompression on the character strings. The provided index data storage method has the characteristics of being simple in structure, compact in data, quick in query speed and friendly to combination query computation.
