Research And Implementation Of Hybrid Search Based On WEB Platform

With the rapid development of information technology, it is more and moreintense that users obtain needs of rapid and comprehensive information by networksearch. It also becomes a hot spot that we achieve rapid and comprehensive searchresults. Currently, however, the major search engines return the results ratio less than40%, moreover these search engines have the different of the mechanism, scope, thealgorithm and so on, so these lead to a query results of repeat rates less than 34% whenwe query the same queries in different search engines. Therefore, in order to get toresults which are more comprehensive, accurate and fast, we must be repeated callingmany search engines, and this will affect the inquiry speed and response time. To avoidthese kinds of repeated calling, the thesis meets the user's information demandsthrough the integration of web pages search and shopping search.The project is the integration of application based on WEB platform, and it isrealized to two functions which are web searching and shopping searching, in webintegrated Google, Baidu, Soso and Youdao, shopping integrated Youdao and Taobao.Concretely speaking, we through the requirement construct the URL which comesfrom the original site, then we do web crawler and data items extraction, and finally wedo repeat, having cache, and it is displayed to the user, at last the users can be quicklyfind multiple web sites on one system. It is realized to quick search as a WEBframework to Struts2, using Ibatis as a data access layer component, and making use ofEHcache as a distributed caching framework.Firstly the thesis is introduced to the background of hybrid search, the currentsituation of domestic and international, and the project sources and researchsignificance; Secondly, it is told that the concept and advantages of hybrid search, the relevant technology of hybrid search; And then focuses on the analysis of thesetechniques in project application;The next detailedly discussed to hybrid search of theoverall design, including requirements analysis, database design, total structure and theapplication of MVC design pattern; Subsequently, analysed the project developmentprocess and the implementation details; And introduced the project testing methodsand results.Finally the thesis is realized to the way when the users input keywords, we mayobtain no-repeated, comprehensive, fast and accurate search information from Google,Baidu, Soso and Youdao, and then with the whole unified format presented to the users.Similarly, shopping is also realized to the desired function. It still exists manyinsufficiencies. So we will sustain webpage-friendly, the realization of the rest of thehot classification search and advertising module management and so forth.
