es嵌套和普通条件一起进行查询

        BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
        QueryBuilder termQueryBuilder1 = QueryBuilders.termQuery("last_name", "smith");
        //嵌套类型查询
        QueryBuilder tags = QueryBuilders.nestedQuery("tags", QueryBuilders.termQuery("tags.userid", "1a"), ScoreMode.Total);
        boolQueryBuilder.must(tags);
        boolQueryBuilder.must(termQueryBuilder1);
        searchRequestBuilder.setQuery(boolQueryBuilder);
        SearchResponse searchResponse = searchRequestBuilder.execute().actionGet();
