package com.wxf.Test;/** * @Auther: wxf * @Date: 2018/6/29 15:46 */public class Test { public static void main(String[] args) throws Exception { IndexCRUD indexCRUD=new IndexCRUD(); // indexCRUD.setUp(); indexCRUD.testIndexWriter(); indexCRUD.testIndexReader(); indexCRUD.select("name", "黑"); }}
indexCRUD.setUp() 这个方法 调一次就可以了 结果如下
这次换个范围大的查询参数
public class Test { public static void main(String[] args) throws Exception { IndexCRUD indexCRUD=new IndexCRUD(); // indexCRUD.setUp(); indexCRUD.testIndexWriter(); indexCRUD.testIndexReader(); indexCRUD.select("name", "强化"); }} 结果如下：
这里采用一元分词 可以随意匹配
