No exaggeration to say that all users can be reached any one place on the Inter by the aid of search engines. So it has bee the most using online services for people except Email. However, with the rapid development of the Inter, the contradictions between massive information and obtaining the capacity of required information is obvious day by day. Searching for information in vast work resources is like looking for needles in a haystack, but search engine just solves this problem. The software is about web music search. It uses java to develop a simple Inter music search engine, and also gathers the reptile (intrabuilder java multithread and socket technology) and web search based on B/S construction (struts framework) as a whole search software. It can achieve the collection, analysis, classification, storage and search of Inter music information. Through the test and analysis, it shows this system is stable, reliable, and has some practical values. Key words: Music。 大約在 1996 年出現(xiàn)的第二代搜索引擎系統(tǒng)大多采用分布式方案（多個(gè)微型計(jì)算機(jī)協(xié)同工作）來(lái)提高數(shù)據(jù)規(guī)模、響應(yīng)速度和用戶數(shù)量，它們一般都保持一個(gè)大約 50， 000， 000網(wǎng)頁(yè)的索引數(shù)據(jù)庫(kù)，每天能夠響應(yīng) 10， 000， 000次用戶檢索請(qǐng)求。 2 Web音樂(lè)搜索軟件的需求分析 隨著因特網(wǎng)的迅猛發(fā)展、 WEB信息的增加，用戶要在信息海洋里查找信息，就像大海撈針一樣，搜索引擎恰好解決了這一難題（它可以為用戶提供信息檢索服務(wù)）。 3 Web音樂(lè)搜索軟件的設(shè)計(jì) 根據(jù)上一章需求分析的情況，結(jié)合本軟件所要需實(shí)現(xiàn)的功能，進(jìn)行設(shè)計(jì)。 Tomcat Server 是根據(jù) servlet和 JSP規(guī)范進(jìn)行執(zhí)行的，因此我們就可以說(shuō) Tomcat Server 也實(shí)行了 ApacheJakarta 規(guī)范且比絕大多數(shù)商業(yè)應(yīng)用軟件服務(wù)器要好。 雖然這里只描述了一個(gè)隊(duì)列，但在實(shí)際編程中用到了 二 個(gè)隊(duì)列，每個(gè)隊(duì)列都保存著同一處理狀態(tài)的 URL。 Search sea=null。 () 0){ // 從頁(yè)面中獲取有效的鏈接 ana=new Analyzer(pageContents,url)。 (sql)。其中最簡(jiǎn)單的是 URL(String url)，它有一個(gè) String類型的參數(shù)，把 URL分解為自己的組件，并把這些組件存儲(chǔ)在一個(gè)新的 URL對(duì)象中。//保存在網(wǎng)絡(luò)緩沖區(qū)中 } setMessage(sumstring)。此時(shí)，只有方括號(hào)里面指定的字符才參與匹配。 p = (oristring,)。在解決如何解析之前，先來(lái)介紹HTML中的幾種數(shù)據(jù) 。)0amp。 } } catch(StringIndexOutOfBoundsException e ){ } if((/)){ /*int m=(/)。 t[i].start()。對(duì)于更為復(fù)雜的 Web 應(yīng)用， JavaBean 組件可以作為 EJB 或 Web 服務(wù)的前端組件 (組件Database 采用數(shù)據(jù)庫(kù)連接池技術(shù)有效的利用率數(shù)據(jù)資源 )。 String lastpage_af= 39。mode=+mod+amp。 pageview+=(i)+process_enu+(i)。 參考文獻(xiàn) [1] Andrew [M].北京：清華大學(xué)出版社， 1998。 除非另有科研合同和其他法律文書(shū)的制約，本論文的科研成果屬于成都信息工程學(xué)院。 and so he fretted and worried himself till at last the unhappy man fretted himself into the grave. Here rests a happy man, that is to say, a man of high birth and position, which was very lucky for him, otherwise he would ha ve been scarcely worth notice. It is beautiful to observe how wisely nature orders these things. He walked about in a coat embroidered all over,and in the drawingrooms of society looked just like one of those rich pearlembroidered bellpulls, which are only made for show。 there rests a very unhappy man, and yet while he lived he might be said to occupy a very good position. He had enough to live upon, and something to spare。 （ 2）學(xué)?？梢圆捎糜坝?、縮印或其他復(fù)制方式保存學(xué)位論文。為了保證用戶查找信息的 精確 度和新鮮度， 搜索引擎需要建立并維護(hù)一個(gè)龐大的索引數(shù)據(jù)庫(kù)。i=sum。 String after_enu=/a/span/FONT/TDTD vAlign=bottom noWrap /TD。 String lastpage_be=TD vAlign=bottom noWrapFONT size=1a href=39。同樣要拷貝到 WEBINF\lib 下 第 1
