  本文選題：混合搜索　切入點：Struts2　出處：《西安建筑科技大學》2011年碩士論文

【摘要】：隨著信息技術的疾速發(fā)展，用戶通過網(wǎng)絡搜索獲得快速、全面信息的需求越來越強烈。實現(xiàn)快速的、全面的搜索結果也成為一個研究熱點。由于目前主要的搜索引擎返回結果的比率不足40％，而且各個搜索引擎有著不同的機制、算法、范圍等，所以導致同樣一個查詢請求在不同的搜索引擎中查詢結果的重復率不足34％。因此，要想獲得一個比較全面的、準確的、快速的結果，就必須反復調用多個搜索引擎，這樣會影響用戶查詢效率。為了避免這種反復調用的情況，MySearch項目通過整合網(wǎng)頁和購物搜索滿足用戶的信息需求。 本項目是一個基于WEB平臺的整合應用，實現(xiàn)了網(wǎng)頁搜索和購物搜索兩大功能，其中網(wǎng)頁整合了谷歌、百度、搜搜和有道，購物整合了淘寶和有道。具體來講，通過搜索條件構造原網(wǎng)站的URL，然后對原網(wǎng)站進行網(wǎng)頁抓取和數(shù)據(jù)項的抽取，最后對數(shù)據(jù)進行去重、緩存，并顯示給用戶，讓用戶在一個網(wǎng)頁上可以很迅速的查找多個網(wǎng)站的信息。該項目以Struts2作為WEB框架，使用Ibatis作為數(shù)據(jù)訪問層組件，，應用EHcache作為分布式緩存框架，實現(xiàn)快速搜索。 論文首先介紹了混合搜索的研究背景、國內外的發(fā)展現(xiàn)狀以及項目來源和研究意義；其次，簡要介紹了混合搜索的概念和優(yōu)勢、混合搜索的相關技術；重點分析了這些技術在項目中的應用；接下來詳細地介紹了混合搜索的總體設計，包括需求分析、數(shù)據(jù)庫設計、項目的總體結構和MVC設計模式的應用；最后，介紹了項目開發(fā)過程和實現(xiàn)細節(jié)；以及介紹項目進行測試的方法及結果。 本項目最終實現(xiàn)了用戶在網(wǎng)頁搜索框中輸入關鍵詞時，就可以獲得來自谷歌、百度、搜搜和有道主流搜索引擎中不重復的、全面的、快速的、準確的信息，并以整體統(tǒng)一的格式呈現(xiàn)給用戶。同樣，購物也實現(xiàn)了預設的功能。項目中還存在著一定的不足，在今后的開發(fā)和維護中，將會不斷改進頁面的友好性，熱門分類搜索的實現(xiàn)，及廣告模塊的管理等等。
[Abstract]:With the rapid development of information technology, users need more and more comprehensive information through network search.Achieving fast and comprehensive search results has also become a research hotspot.At present, the main search engines return less than 40% of the results, and each search engine has different mechanisms, algorithms, scope and so on, so the repeat rate of the same query request in different search engines is less than 34%.Therefore, in order to obtain a more comprehensive, accurate and fast result, multiple search engines must be repeatedly called, which will affect the efficiency of user query.To avoid this kind of repeated calls, the MySearch project meets users' information needs by integrating web pages and shopping searches.This project is an integrated application based on WEB platform, which realizes two functions of web search and shopping search, among which web pages integrate Google, Baidu, Sosou and youdao, and shopping integrates Taobao and youdao.Specifically, the URLL of the original website is constructed by searching conditions, then the original website is fetched and the data items are extracted. Finally, the data is removed, cached, and displayed to the user.Allows users to quickly find information on multiple sites on a single page.This project uses Struts2 as WEB framework, Ibatis as data access layer component and EHcache as distributed cache framework to realize fast search.Firstly, this paper introduces the research background of hybrid search, the development status at home and abroad, the source of the project and the significance of the research; secondly, it briefly introduces the concept and advantages of hybrid search, and the related technologies of hybrid search.The application of these technologies in the project is analyzed in detail. Then, the general design of hybrid search is introduced in detail, including requirement analysis, database design, the overall structure of the project and the application of MVC design pattern.This paper introduces the development process and implementation details of the project, as well as the methods and results of the project testing.This project has finally realized that when users enter keywords in the web search box, they can obtain non-repetitive, comprehensive, fast and accurate information from Google, Baidu, Soso and youdao mainstream search engines.And the overall unified format presented to the user.Similarly, shopping also achieves the preset function.There are still some deficiencies in the project, in the future development and maintenance, will continue to improve the friendliness of the page, the implementation of popular classification search, and advertising module management and so on.
