全文检索已经越来越像样了，不过还是发现很多问题，这玩意有些逻辑问题没想通。。

有三个字段参与检索：query1，query2，query3

这里设置它的逻辑关系如果只是单个的设置没啥问题，可是我想实现如：

SELECT * FROM TABLENAME WHERE （query1 like '%测试%' or query2  like '%测试%') and  query3 like '%测试%'

  IndexSearcher search = new IndexSearcher(indexpath);          

  QueryParser qp1 = new QueryParser("title", new StandardAnalyzer());           

Query query1 = qp1.Parse(querystring);           

QueryParser qp2 = new QueryParser("Content", new StandardAnalyzer());            Query query2 = qp2.Parse(querystring);           

QueryParser qp3 = new QueryParser("tableName", new StandardAnalyzer());            Query query3 = qp3.Parse("异国文化");           

BooleanQuery query = new BooleanQuery();           

 query.Add(query1, BooleanClause.Occur.SHOULD);           

query.Add(query2, BooleanClause.Occur.SHOULD);           

query.Add(query3, BooleanClause.Occur.MUST);      

query.Add(query1, BooleanClause.Occur.SHOULD);      

query.Add(query2, BooleanClause.Occur.SHOULD);      

query.Add(query3, BooleanClause.Occur.MUST);
想实现先OR 再 AND查询 我这里的关键词应该怎么设置呢？
