java - QueryString 用冒号搜索字符串

Question

我正在努力实现以下条件

orgId =“z2store”，类型 =“web”，日期时间 =“12:17:08”

下面是我写的查询

GET /sample/_search
{
  "bool" : {
    "must" : [
      {
        "term" : {
          "orgId" : {
            "value" : "z2store",
            "boost" : 1.0
          }
        }
      },
      {
        "term" : {
          "type" : {
            "value" : "web",
            "boost" : 1.0
          }
        }
      },
      {
        "query_string" : {
          "query" : "12:17:08",
          "default_field" : "dateTime",
          "fields" : [ ],
          "type" : "best_fields",
          "default_operator" : "or",
          "max_determinized_states" : 10000,
          "enable_position_increments" : true,
          "fuzziness" : "AUTO",
          "fuzzy_prefix_length" : 0,
          "fuzzy_max_expansions" : 50,
          "phrase_slop" : 0,
          "escape" : false,
          "auto_generate_synonyms_phrase_query" : true,
          "fuzzy_transpositions" : true,
          "boost" : 1.0
        }
      }
    ],
    "adjust_pure_negative" : true,
    "boost" : 1.0
  }
}

下面是我的java代码

BoolQueryBuilder boolQuery = new BoolQueryBuilder().must(QueryBuilders.termQuery("orgId", orgId))
                        .must(QueryBuilders.termQuery("type", "web"));
QueryStringQueryBuilder builder = new QueryStringQueryBuilder("12:17:08");
                        builder.defaultField("dateTime").queryString();
                        boolQuery.must(builder);
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder().query(builder)
                        .from((batchNumber - 1) * batchSize).size(batchSize)
                        .sort("@timestamp", SortOrder.DESC);

以上查询不起作用。任何帮助将不胜感激。我使用的是elasticSearch 7.4。

您可以创建 dateTime 字段，类型为 date，格式为 hour_month_second(格式为 HH:mm:ss) 。您可以在此处了解有关不同日期格式的更多信息 https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-date-format.html .

下面是dateTime字段的映射:

{
    "mappings": {
        "properties": {
            "dateTime": {
                "type" : "date",
                "format" : "hour_minute_second"
            }
        }
    }
}

现在，当您使用以下搜索查询搜索数据时:

{
    "query" : {
        "bool" : {
    "must" : [
      {
        "term" : {
          "orgId" : {
            "value" : "z2store",
            "boost" : 1.0
          }
        }
      },
      {
        "term" : {
          "type" : {
            "value" : "web",
            "boost" : 1.0
          }
        }
      },
      {
       "term" :{
        "dateTime":"12:17:08"
       }
      }
    ],
    "adjust_pure_negative" : true,
    "boost" : 1.0
  }
    }

}

您将得到所需的结果:

"hits": [
            {
                "_index": "datetimeindexf",
                "_type": "_doc",
                "_id": "1",
                "_score": 1.5753641,
                "_source": {
                    "dateTime": "12:17:08",
                    "orgId": "z2store",
                    "type": "web"
                }
            }
        ]
