Searching method and system for preprocessing keywords

Abstract

The invention relates to searching method and system for preprocessing keywords. The method comprises the following steps of: receiving keywords input by a user; carrying out word segmentation processing on the keywords to further generate a word segmentation processing result; retrieving the word segmentation processing result in title index library corresponding to a title library by adopting afirst logical operation, thus further obtaining titles containing the keywords; and carrying out combined retrieval on the word segmentation processing result and the titles containing the keywords in a content index library by adopting a second logical operation, and outputting a search result. According to the invention, the needed content can be accurately and fast searched and the experience of a user is greatly improved by preprocessing the keywords input by the user, adopting a word segmentation technology and an index technology to directly find contents and titles entirely containing keywords input by the user, then adding the tiles into the user searching keywords for carrying out combined search, and ensuring the keywords input by the user to entirely appear in the titles of thecontents and be highly ranked in the searched results.

Description

technical field [0001] The invention relates to user search technology, more specifically, to a search method and system for preprocessing keywords. Background technique [0002] Most of the current Chinese search engines are based on the method of Chinese thesaurus to realize index creation and keyword search. From the perspective of search effect and performance, it is impossible for this traditional search method to index and store all the words in the search content source. In this way, users cannot accurately search for the content they need if they only input individual Chinese characters or a few words without knowing the specific content title. Even if they find the desired content, the time spent There are also many, which will eventually affect the user's search experience. [0003] Therefore, there is a need for a search solution that can overcome the defect in the prior art that it is difficult to accurately and quickly search for desired content. Contents of ...
