java+lucene中文分詞，搜尋引擎搜詞剖析

我想只要是學過資料庫的孩紙，不管是mysql，還是sqlsever，一提到查詢，本能的想到的便是like關鍵字，其實去轉盤網（分類模式）之前也是採用這種演算法，但我可以告訴大家一個很不幸的事情，like匹配其實會浪費大量的有用資源，原因這裡不說了請自己想一想，我們還是直接擺事實驗證。

現在用去轉盤網搜：hello 找個單詞，如下：

翻頁你會發現只要是包含hello的單詞都找到了，但是如果你用like的話是不會有這個效果的，不信讓我們再看一下，還好他來說電影網的分詞演算法我還沒來得及修改，還可以看到現象：

你會發現只有開始包含hello這個欄位的搜尋串才能得到匹配，這就問題來了，資料庫中大量的資源豈不是白白浪費了，不過沒事，偉大的人類還是很聰明的，發明了分詞，分詞的原理我就不講了，請自己百度吧，還是直接上程式碼，提示，這裡需要四個jar包作為工具，我先上傳的去轉盤，想要做分詞的請先下載：

注意由於去轉盤網（http://www.quzhuanpan.com)是部署到linux上的，所以DISC_URL可以更具系統變換，我是通過url來判定索引檔案是否唯一的，你可以更具id來判斷，具體情況具體對待吧。

資料庫之類的請不要關心，看思路即可，你如果需要換成你的即可，這裡就不多說了。

看最後的部分：

package com.tray.indexData;
 
import java.sql.SQLException;
 
 
 
public class Application {
     
    public static void main(String[] args){
        /*IndexFile indexFile=new IndexFile();
        indexFile.indexInit();
        try {
            indexFile.Index6Data();
        } catch (SQLException e1) {
            e1.printStackTrace();
        }
        indexFile.indexEnd();*/
         
        IndexFile indexFile1=new IndexFile();
        indexFile1.indexInit();
        try {
            indexFile1.Index3Data();
        } catch (SQLException e1) {
            e1.printStackTrace();
        }
        indexFile1.indexEnd();
         
        LuceneSearch lch=new LuceneSearch();
        try {
            long a = System.currentTimeMillis();
            lch.highLightSearch("name", "flv", 1,3);
            long b = System.currentTimeMillis();
            long c = b - a;
            System.out.println("[高階檢索花費時間：" + c + "毫秒]");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
