如何使用 Java Api 在 ElasticSearch 中执行 bool 查询？

Question

我正在尝试针对我的 elasticSearch 发送 bool 查询，以过滤掉文档。如何在 Java 中使用 BooleanQueryBuilder Api 过滤布尔表达式，如 (A AND B AND C) AND (D OR E OR F) AND G？我尝试使用过滤器方法，但没有得到任何结果。例如：

例如，假设 A、B、C、D、E、F、G 是属性“name”必须匹配“Robin”的事件。

private QueryBuilder getQueryBuilder() {

        BoolQueryBuilder boolQueryBuilder1 = QueryBuilders
                .boolQuery()
                .filter(QueryBuilders.matchQuery(D).operator(Operator.OR))
                .filter(QueryBuilders.matchQuery(E).operator(Operator.OR))
                .filter(F);

        BoolQueryBuilder boolQueryBuilder2 = QueryBuilders
                .boolQuery()
                .filter(QueryBuilders.matchQuery(A).operator(Operator.AND))
                .filter(QueryBuilders.matchQuery(B).operator(Operator.AND))
                .filter(QueryBuilders.matchQuery(C));

        BoolQueryBuilder boolQueryBuilder3 = QueryBuilders
                .boolQuery()
                .filter(G);

        BoolQueryBuilder boolQueryBuilder = QueryBuilders
                .boolQuery()
                .filter(boolQueryBuilder1)
                .filter(boolQueryBuilder2)
                .filter(boolQueryBuilder3);

        return boolQueryBuilder;

}

我知道这个例子不是很好，但我希望你能帮助我！谢谢！

这是一个吗？

private static QueryBuilder getQueryBuilder() {
    //condition
    MatchQueryBuilder A = QueryBuilders.matchQuery("content", "A");
    MatchQueryBuilder B = QueryBuilders.matchQuery("content", "B");
    MatchQueryBuilder C = QueryBuilders.matchQuery("content", "C");
    MatchQueryBuilder D = QueryBuilders.matchQuery("content", "D");
    MatchQueryBuilder E = QueryBuilders.matchQuery("content", "E");
    MatchQueryBuilder F = QueryBuilders.matchQuery("content", "F");
    MatchQueryBuilder G = QueryBuilders.matchQuery("name", "Robin");
    //Maybe you should use TermQuery
    //TermQueryBuilder G = QueryBuilders.termQuery("name", "Robin");


    //1.(A AND B AND C)
    BoolQueryBuilder query1 = QueryBuilders.boolQuery();
    query1.must(A).must(B).must(C);

    //2.(D OR E OR F)
    BoolQueryBuilder query2 = QueryBuilders.boolQuery();
    query2.should(D).should(E).should(F);

    //3.Last
    BoolQueryBuilder lastQuery = QueryBuilders.boolQuery();
    lastQuery.must(query1).must(query2).must(G);
    
    //use filter
    BoolQueryBuilder filterBuiler = QueryBuilders.boolQuery().filter(lastQuery);
    return filterBuiler;
}
