摘要

A computer-readable recording medium stores therein an information searching program that causes a computer having access to archives including a compressed file group of compressed files that are to be searched and that have described therein character strings, to execute: sorting the compressed files in descending order of access frequency of the compressed files; combining the compressed files in descending order of access frequency after the sorting at the sorting such that a storage capacity of a cache area for a storage area that stores therein the compressed file group is not exceeded by a combined size of the compressed files combined; and writing, from the storage area into the cache area, the compressed files combined at the combining, the compressed files combined being written prior to a search of the compressed files combined.

主权项

1. A non-transitory computer-readable recording medium storing therein an information searching program that causes a computer accessible to a plurality of compressed files to execute a process comprising:
receiving a searching character string; selecting a plurality of specific compressed files from the plurality of compressed files by a character appearance map and a plurality of characters included in the searching character string, the character appearance map including character presence information of individual characters in each of the plurality of specific compressed files; examining whether the plurality of specific compressed files is in a cache area or a storage area utilizing a file access information; the file access information including an access frequency, caching status, accessing address in the cache area, and a file size for each of the plurality of specific compressed files; accessing a selected specific compressed file utilizing the accessing address and the file size in the file access information when the specific compressed file is in the cache area; accessing the specific compressed file in the storage area when the specific compressed file is not in the cache area; decompressing the specific compressed file; and searching the searching character string in the decompressed specific compressed file, the access frequency of the specific compressed file in the file access information being increased when the decompressed specific file includes the searching character string.
