Question

我需要使用Jest客户端进行Elasticsearch查询，以匹配某些术语，并使用范围查询来创建日期。所以我需要使用Jest QueryBuilder使用范围查询执行bool查询，以获得如下请求：

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

}

为此，我做了一个像这样的queryBuilder：

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");
}

我的问题是，如何在searchbuilder上添加范围查询，因为我的对象qb已经有了boolquery，我无法为此添加范围查询。

试试这个。

               QueryBuilder rangeQuery = QueryBuilders
                .rangeQuery("field")
                .from("2016-01-01||/D")
                .to("2017-01-01||/D")
                .includeLower(true)
                .includeUpper(false);



                QueryBuilder termsQuery = QueryBuilders.boolQuery()
                .must(QueryBuilders.termsQuery("field1","12"))
                .must(QueryBuilders.termQuery("field2", "abc"))
                .must(QueryBuilders.termQuery("field3", "def"));


                QueryBuilder qb = QueryBuilders
                .boolQuery()
                .should(rangeQuery)
                .should(termsQuery);

Answer 2

您需要一个范围查询，如下所示：

QueryBuilder rangeQ = QueryBuilders
                    .rangeQuery("begindate")
                    .from(5)
                    .to(10);

然后将两个查询与should：

组合在一起

QueryBuilder qb = QueryBuilders
                    .boolQuery()
                    .should(rangeQ)
                    .should(boolQ);
