elasticsearch must和should组合查询

Es查询，解构类似：  A & (a & b & c) or (c & e) 

JavaAPI写法：

BoolQueryBuilder query = QueryBuilders.boolQuery();

BoolQueryBuilder q1 = QueryBuilders.boolQuery();
    q1.must(QueryBuilders.termQuery("flag_best", 1));
    q1.must(QueryBuilders.termQuery("flag_fornew", 1));
    q1.must(QueryBuilders.termQuery("flag_off",0));

BoolQueryBuilder q2 = QueryBuilders.boolQuery();
    q2.must(QueryBuilders.prefixQuery("sub_category", "sub"));
    q2.must(QueryBuilders.termQuery("flag_reviewed", 1));
    q2.must(QueryBuilders.termQuery("flag_off",0));

query.should(q1); 
query.should(q2);

注意：如果此处存在一个共同的查询值,如flag_off，那么一定要在两个query中分别写出
写成【query.must(QueryBuilders.termQuery("flag_off",0))】将会产生错误

错误写法：(写法本身有问题，并且不能在后面连续进行must会溢出。应参照文章最后JSON结构来写Java代码)

query.should(QueryBuilders.boolQuery().must(QueryBuilders.termQuery("flag_best",1)).must(QueryBuilders.termQuery("flag_fornew",1)).must(QueryBuilders.termQuery("flag_off",0)));
query.should(QueryBuilders.boolQuery().must((QueryBuilders.prefixQuery("sub_category","sub"))).must(query.must(QueryBuilders.termQuery("flag_reviewed", 1)).must(QueryBuilders.termQuery("flag_off",0))));
