Abstract

This application is applicable to the technical field of data processing, and provides a data query method, terminal equipment, and a computer-readable storage medium, including: obtaining a search keyword, searching a target linked list corresponding to the first character of the search keyword from the cache; detecting Whether there is a target index matching the search keyword in the target linked list; if there is no target index matching the search keyword in the target linked list, search and obtain the target index matching the search keyword from the disk; The index is added to the target linked list in the cache, and the suffix string corresponding to the target index is output; if there is a target index matching the search keyword in the target linked list, the suffix string corresponding to the target index is obtained and output, thereby improving the Data query efficiency shortens the data query time.

Description

technical field [0001] The present application belongs to the technical field of data processing, and in particular relates to a data query method, a terminal device and a computer-readable storage medium. Background technique [0002] The search engine based on the suffix index is a search engine based on the suffix string of the string as the index. The existing search engine based on the suffix index usually stores the index in the disk. In this way, each time the terminal device processes a query request, it needs to All indexes are loaded from the disk into the memory, and then the indexes that meet the requirements are searched from the indexes loaded into the memory. However, since most of the indexes stored in the disk are rarely retrieved, loading all the indexes into the memory every time a query request is processed will reduce the efficiency of data query and prolong the time of data query. Contents of the invention [0003] In view of this, the embodiment of ...
