Distributed indesx file searching method, searching system and searching server

Abstract

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 .

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a retrieval method, retrieval system and retrieval server of a distributed index file. Background technique [0002] Usually, a search string needs to be input when performing a search. The search string contains one or more keywords, and each keyword is composed of one or more morphemes. A morpheme is the smallest language unit capable of expressing independent semantics. It is usually a Chinese word segmented in a word segmentation system; a keyword can be segmented into a number of morphemes through the word segmentation system. If it is divided into two morphemes, the keyword A word is a binary compound morpheme. If it is divided into three morphemes, the keyword is a triple compound morpheme; each keyword in the search string is separated by a space. Usually, in Internet searches, keywords The spaces in the symbol represent the retrieval operation of "AND" bet...
