Analysis Research And Implementation Of Search Engine

Search engine is one of the Internet information resources classification and search,and storage exists in network database for users to query the system,its main principle is using web crawlers by certain strategies to crawl the web page data,again after processing and analysis.Finally,the capture of key data stored in the index,when users to search,it through some sort of method eventually related result is presented to the user.This paper briefly introduces the search engine's development history,classification,component parts and its working principle,I after in-depth research and Analysis on it.rely on Java open source framework Lucence the search engine program written,including crawling,indexing andsorting.In this design,we use the spider to catch a large of datas from the internate,and insert into the database.we can use the open source framework“Lucence” to index the data after analysis it.when someone use the search engine,the search string will be Processed by the paoding word participle equitment in order to combined into a new query string which the compass framework can use it easily to get the datas in the index database.when we get the datas,how to sort it is the importment thing that we must do next.In this design,I use the follow method:Get the first 500 records which was indexed to sort by myselves' method and return the most usefull message to the user.
