//FooManager.java（做全文检索示例）

package com.itone.search.manager;

import java.util.List;

import org.apache.lucene.analysis.StopAnalyzer;
import org.apache.lucene.queryParser.QueryParser;
import org.apache.lucene.search.Query;
import org.hibernate.search.FullTextQuery;
import org.hibernate.search.FullTextSession;

import com.itone.search.pojo.Foo;

public class FooManager extends BaseManager<Foo> {

@SuppressWarnings("unchecked")
public void testQuery() throws Exception {
     QueryParser parser = new QueryParser("name", new StopAnalyzer());
     Query luceneQuery = parser.parse("name:Jack");
     FullTextSession s = Search.createFullTextSession(getSession());
     FullTextQuery query = s.createFullTextQuery(luceneQuery, Foo.class);
     List<Foo> result = query.list();
     for(Foo f : result) {
      System.out.println("ID:" + f.getId());
      System.out.println("NAME:" + f.getName());
      System.out.println("CONTENT:" + f.getContent());
      System.out.println("POSTTIME:" + f.getPostTime());
     }
}
}

看你上面的代码实在是太麻烦了。还不如直接用lucene写！
spring真的是把简单问题复杂化。

嗯，我最近的商用测试也发现，hibernate search包装的很烂，只是实现在功能而已。在商业用途上还是有很大的问题。比如：用FullTextQuery来list的时候，生成的sql语句是：select ... from Foo where id in(?,?,?...) or id in (?, ?, ?...) or ...这样，对于结果集很大的情况（如32768条）就很慢了。

为什么不会自己建立索引，更新，添加，也全部不会建立或更新索引，是怎么回事啊
