java+lucene中文分詞，搜索引擎搜詞剖析

我想只要是學過數據庫的孩紙，無論是mysql，仍是sqlsever，一提到查找，本能的想到的即是like關鍵字，其實去轉盤網（分類模式）以前也是採用這種算法，但我能夠告訴你們一個很不幸的事情，like匹配其實會浪費大量的有用資源，緣由這裏不說了請本身想想，咱們仍是直接擺事實驗證。

如今用去轉盤網搜：hello 找個單詞，以下：

翻頁你會發現只要是包含hello的單詞都找到了，可是若是你用like的話是不會有這個效果的，不信讓咱們再看一下，還好他來講電影網的分詞算法我還沒來得及修改，還能夠看到現象：

你會發現只有開始包含hello這個字段的搜索串才能獲得匹配，這就問題來了，數據庫中大量的資源豈不是白白浪費了，不過沒事，偉大的人類仍是很聰明的，發明了分詞，分詞的原理我就不講了，請本身百度吧，仍是直接上代碼，提示，這裏須要四個jar包做爲工具，我先上傳的去轉盤，想要作分詞的請先下載：

注意因爲去轉盤網（http://www.quzhuanpan.com)是部署到linux上的，因此DISC_URL能夠更具系統變換，我是經過url來斷定索引文件是否惟一的，你能夠更具id來判斷，具體狀況具體對待吧。
