Method and system for searching network

Abstract

A searching method of network includes using multi-element composite morpheme with multiple morpheme as indexing word to set up file-indexing, dividing index key word inputted by user to be a multi-element composite morpheme and carrying out network search according to divided multi-element composite morpheme.

Description

technical field [0001] The invention belongs to the field of network search, in particular to a network search method and system. Background technique [0002] In network search, the search expression entered by the user is a search string, and the search string can contain one or more keywords, separated by spaces, which means that the keywords before and after it will be logically ANDed (AND). A keyword is a string composed of one or more morphemes, which can be further segmented through the word segmentation system. If 2 morphemes are segmented, the keyword is called a 2-element compound morpheme, and if 3 morphemes are segmented, the keyword is called a 3-element compound morpheme. A morpheme is the smallest language unit capable of expressing independent semantics, and it is indivisible. In Chinese, a morpheme is a Chinese word segmented in the word segmentation system, and in English, a morpheme is a basic English word or letter. [0003] When searching on the Inter...
