Problems solved by technology

Its disadvantages are: the split granularity of search terms is small, the number of index queries and set operations of search engines is large, the system query efficiency is low, and the search speed is low
Due to the above shortcomings, it is impossible to create too many indexes, at most three elements, because the space expansion is too strong, resulting in insufficient index

Embodiment Construction

[0020] The present invention will be further elaborated below according to the drawings and specific embodiments.

[0021] Such as figure 1 As shown, the search system 10 includes a web page crawling module 100 , a web page database 200 , an index module 300 , an index database 400 and a search module 500 connected in sequence.

[0022] Wherein, the webpage crawling module 100 is responsible for automatically extracting information from the Internet, and storing the extracted information in the webpage database 200 . The general method is: the web crawling module 100 automatically accesses the Internet through a web spider program that can automatically collect web pages from the Internet, and crawls to other web pages along all URLs (uniform resource locators) in any web page, repeating this process , and collect all the web pages crawled into the web page database 200 . There are two types of automatic information collection functions of search engines, one is regular sear...

Abstract

The invention discloses a searching method, which comprises the following steps on establishing and updating index data base: A1.accounting various combination frequencies of the effective entry in the input web text; A2.establishing index for the complex word (the frequency of the complex word is more than setting threshold value). The invention also discloses a searching system. The invention reduces the resolution particle size of the searching word when searching, which reduces the index inquiring times of searching engine and the times of accounting intersection set and union, improves the searching speed of the searching engine, achieves the aim of answering the user quickly, improves availability ratio of the index data base and accuracy ratio of the system searching.

Description

technical field [0001] The invention relates to computer technology, in particular to a search method and system. Background technique [0002] With the rapid development of the Internet, all kinds of information are increasing explosively. Users want to find information in the ocean of information, just like looking for a needle in a haystack. Every Internet user faces the problem of information overload, and cannot find exactly the information he needs. The search engine is a technology that appears to solve this "trek" problem. The navigation service provided by the search engine has become a very important network service on the Internet, and has become the most important Internet application alongside e-mail. Search engines provide users with information "retrieval" services, which use spider programs to classify all information on the Internet to help users search for the information they need in the massive Internet information. The principle of a search engine mai...
