elasticsearch - 如何在Elastic Search中使用Java高级休息客户端执行范围查询？

Question

嗨，我目前有一个 flex 搜索索引，我正在尝试使用java高级rest客户端库对该索引内的文档执行日期范围查询。但是，它没有按预期工作。所以下面是我的索引。我必须对@timestamp字段执行范围查询。

{
  "took" : 6,
  "timed_out" : false,
  "_shards" : {
    "total" : 2,
    "successful" : 2,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : 229081,
    "max_score" : 1.0,
    "hits" : [
      {
        "_index" : "mep-reports-2019.09.11",
        "_type" : "doc",
        "_id" : "68e8e03f-baf8-4bfc-a920-58e26edf835c-353899837500",
        "_score" : 1.0,
        "_source" : {
          "account_id" : "270d13e6-2f4f-4d51-99d5-92ffba5f0cb6",
          "inventory" : "SMS",
          "flight_name" : "test flight 001",
          "status" : "ENROUTE",
          "msg_text" : "Test !!!!!!!!!!!!!!1 elastic search:is.gd/YfzotY",
          "flight_id" : "68e8e03f-baf8-4bfc-a920-58e26edf835c",
          "submission_ts" : "1568197286",
          "recipient" : "353899837500",
          "o_error" : null,
          "nof_segments" : "-1",
          "campaign_id" : "0fae8662-bee9-46ac-9b3e-062f4ba55966",
          "campaign_name" : "Index search petri11",
          "@version" : "1",
          "sender" : "800111",
          "delivery_ts" : "0",
          "@timestamp" : "2019-09-11T10:21:26.000Z"
        }
      },
      {
        "_index" : "mep-reports-2019.09.11",
        "_type" : "doc",
        "_id" : "68e8e03f-baf8-4bfc-a920-58e26edf835c-353899837503",
        "_score" : 1.0,
        "_source" : {
          "account_id" : "270d13e6-2f4f-4d51-99d5-92ffba5f0cb6",
          "inventory" : "SMS",
          "flight_name" : "test flight 001",
          "status" : "ENROUTE",
          "msg_text" : "Test !!!!!!!!!!!!!!1 elastic searchh",
          "flight_id" : "68e8e03f-baf8-4bfc-a920-58e26edf835c",
          "submission_ts" : "1568197286",
          "recipient" : "353899837503",
          "o_error" : null,
          "nof_segments" : "-1",
          "campaign_id" : "0fae8662-bee9-46ac-9b3e-062f4ba55966",
          "campaign_name" : "Index search petri11",
          "@version" : "1",
          "sender" : "800111",
          "delivery_ts" : "0",
          "@timestamp" : "2019-09-11T10:21:26.000Z"
        }
      }
}

followign是我的Java代码，试图在@timestamp上进行范围查询，但它不起作用。我仅从名为SearchRequestBuilder的构建器类中粘贴以下范围查询代码段的一部分。

SearchRequestBuilder range(ZonedDateTime startDate, ZonedDateTime endDate) {

    System.out.println(startDate); // 2019-08-31T23:00Z
    System.out.println(endDate);   // 2019-09-17T13:25:18.154Z



    RangeQueryBuilder startRangeQueryBuilder = QueryBuilders.rangeQuery("@timestamp").gte(startDate);
    startRangeQueryBuilder.format("yyyy-MM-dd'T'HH:mm:ss.SSSZ");

    boolQueryBuilder.should(startRangeQueryBuilder);

    RangeQueryBuilder endRangeQueryBuilder = QueryBuilders.rangeQuery("@timestamp").lte(endDate);
    boolQueryBuilder.should(endRangeQueryBuilder);
    endRangeQueryBuilder.format("yyyy-MM-dd'T'HH:mm:ss.SSSZ");

    return this;
}

任何想法我该如何解决我的范围查询，以使其正常工作

the followign is a SearchRequestBuilder that builds an elastic search index

static class SearchRequestBuilder {

        private SearchRequest searchRequest;

        private SearchSourceBuilder searchSourceBuilder;

        private BoolQueryBuilder boolQueryBuilder;

        SearchRequestBuilder(String elasticSearchIndex) {
            this.searchRequest = new SearchRequest(elasticSearchIndex);
            this.searchRequest.indicesOptions(IndicesOptions.lenientExpandOpen());
            this.searchSourceBuilder = new SearchSourceBuilder();
            this.searchRequest.source(searchSourceBuilder);
            this.boolQueryBuilder = QueryBuilders.boolQuery();
            this.searchSourceBuilder.query(this.boolQueryBuilder);
        }

        SearchRequestBuilder from(Integer pageNumber) {
            this.searchSourceBuilder.from(pageNumber);
            return this;
        }

        SearchRequestBuilder size(Integer pageSize) {
            this.searchSourceBuilder.size(pageSize);
            return this;
        }

        SearchRequestBuilder timeOut(long duration, TimeUnit timeUnit) {
            this.searchSourceBuilder.timeout(new TimeValue(duration, TimeUnit.SECONDS));
            return this;
        }

        SearchRequestBuilder range(ZonedDateTime startDate, ZonedDateTime endDate) {

            System.out.println(startDate);
            System.out.println(endDate);
        //  this.boolQueryBuilder.must(QueryBuilders.rangeQuery("@timestamp").from(startDate,true).to(endDate));

            //QueryBuilders.rangeQuery("FieldName").from(startDate,true).to(endDate));


            RangeQueryBuilder startRangeQueryBuilder = QueryBuilders.rangeQuery("@timestamp").gte(startDate);
            startRangeQueryBuilder.format("yyyy-MM-dd'T'HH:mm:ss.SSSZ");

            boolQueryBuilder.should(startRangeQueryBuilder);

            RangeQueryBuilder endRangeQueryBuilder = QueryBuilders.rangeQuery("@timestamp").lte(endDate);
            boolQueryBuilder.should(endRangeQueryBuilder);

            return this;

                    WildcardQueryBuilder msisdnWildCardQueryBuilder = new WildcardQueryBuilder("recipient", msisdn);
                    boolQueryBuilder.must(msisdnWildCardQueryBuilder);
                } else {
                    MatchQueryBuilder matchQueryBuilder = new MatchQueryBuilder("recipient", msisdn);
                    boolQueryBuilder.must(matchQueryBuilder);
                }
            }
            return this;

        SearchRequest build() {

    }

非常感谢

主要问题是未考虑should()子句，因为其他子句是must()(See why here)。如果您使用filter()子句而不是must()，那么它将起作用。
flightId方法的示例如下:

    SearchRequestBuilder flightId(UUID flightId) {
        if (flightId != null) {
            MatchQueryBuilder matchQueryBuilder = new MatchQueryBuilder("flight_id", flightId.toString());
            boolQueryBuilder.filter(matchQueryBuilder);
        }                       ^
        return this;            |
    }                           |
                           change this
