分布式索引文件的检索方法、检索系统及检索服务器

Distributed indesx file searching method, searching system and searching server

Abstract

本发明公开了一种分布式索引文件的检索方法,包括:对获取的检索串进行解析后生成由关键词组成的检索表达式;将所述关键词的检索请求及该关键词的倒排表项的预读请求发送至集群中的各个检索服务器;集群中的检索服务器按照所述关键词命中文档的频率高低读取所述关键词的倒排表项;集群中的检索服务器对所述关键词的倒排表项进行逻辑操作后输出检索结果。本发明还公开了一种分布式索引文件的检索方法和一种分布式索引文件的检索服务器。应用本发明有效提高了检索集群内部检索服务器之间的耦合度,增加了服务器之间的资源动态调配能力,通过把集群内的多台检索服务器的资源进行统一规划,最大限度保证了集群整体的并发能力,提高了检索速度。
The invention discloses a distributed index file retrieval method. Including: access to the search string to generate analytical after a search by keywords of expression will be described in keywords and the search request keywords inverted Table Pre-reading of the request sent to the various clusters retrieval server; retrieval server cluster in accordance with the documents referred to key words hit frequency reader referred to the words inverted table; Retrieval server cluster described in the words of the inverted form of a logic operation after output search results. The invention also openly distributed a document indexing and retrieval method in a distributed index file retrieval server. Application of this invention effectively improve the retrieval server clustering within the coupling between Retrieval, an increase of resources between the dynamic server deployment capabilities, through the cluster of multiple servers access the resources of unified planning, the maximum guarantee set concurrent group as a whole and improve the speed .
