Abstract

The invention provides a search method and device based on bitmap scores. The search method based on bitmap scoring comprises the following steps: preprocessing search keywords; obtaining a plurality of DSL (domain specific language) query statements with a relevancy scoring algorithm according to a predetermined dimension based on the preprocessed search keyword; obtaining bitmap score DSL query statements capable of identifying matching types based on the DSL query statements; and obtaining a search result of the search keyword based on the DSL query statement and the bitmap score DSL query statement.

Description

technical field [0001] The present application relates to the search field, and more specifically, to a bitmap scoring-based search method and device. Background technique [0002] Existing mainstream search engines (such as ElasticSearch, SOLR, etc.) can construct query statements through their respective DSL (Domain Specific Language, Domain Specific Language), so as to perform corresponding searches. [0003] With the complexity of the search business, two methods are usually adopted to meet the customization needs. The first method is to use all the documents that need to be scored as separate fields, add new fields to the index structure of search engines such as ElasticSearch, and achieve overall comprehensive scoring through custom scoring functions. The second method is to extend the search engine and provide the function of returning the matching status of different fields from the search engine; specifically, generally large Internet search companies have self-bui...
