Elasticsearch Java Jest客户端查询生成器范围与布尔查询

我需要使用Jest客户端进行Elasticsearch查询,以便将一些术语和日期与范围查询相匹配。因此,我需要使用Jest对范围查询执行布尔查询 QueryBuilder 有这样的请求:

{
"query": {
    "range": {
        "gte": "begindate",
        "lte": "enddate"
    },
    "bool": {
        "must": [
            {
                "terms": {
                    "field1": [
                        55,
                        99
                    ]
                }
            },
            {
                "terms": {
                    "field2": [
                        450
                    ]
                }
            },
            {
                "terms": {
                    "field3": [
                        11
                    ]
                }
            }
        ]
    }
}

}

为此,我使用 queryBuilder 像这样:

Builder search = null;
Search buildedSearch = null;
SearchResult result = null;

SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
BoolQueryBuilder qb = QueryBuilders.boolQuery();

if (field1 != null) {
    qb.must(QueryBuilders.termsQuery("field1", field1));
}

if (field2 != null) {
    qb.must(QueryBuilders.termsQuery("field2", field2));
}

if (field3 != null) {
    qb.must(QueryBuilders.termsQuery("field3", field3));
}

String query = searchSourceBuilder.query(qb).toString();

if (field != null) {
    search = new Search.Builder(query).addIndex(index).addType(type);
    if (beginIndex != -1) {
        search.setParameter(Parameters.FROM, beginIndex);
    }

    if (endIndex != -1) {
        search.setParameter(Parameters.SIZE, endIndex);
    }

    buildedSearch = search.build();
}

try {
    result = client.execute(buildedSearch);
} catch (IOException e) {
    LOGGER.info("Can't found result");
}

如何在搜索生成器上添加范围查询,因为我的对象 qb 已经有一个布尔查询,我无法向其中添加范围查询。
