Question

我想获得dateofbirth有子串“-11-09”的所有文件。

这是我的弹性搜索查询：

{ "query": { "bool" : { "must": { "match": { "dobdata": ".*-11-09.*"} } } } }

我得到的结果是

{
 "took": 8,
 "timed_out": false,
 "_shards": {
  "total": 5,
  "successful": 5,
  "failed": 0
 },
 "hits": {

我正在获取dateofbirth不包含字符串“-11-09”的记录。我试图解决它。我无法找到灵魂。

我是elasticsearch的新手。我只想要第一张唱片。任何人都可以帮助我。抱歉英文不好。

Answer 1

即使我遇到同样的问题，我也做了两件事来解决它。 1.将出生日期的格式从Y-m-d更改为YMd，并将索引设为not_analyzed。 2.使用通配符查询而不是匹配查询

{
"query": {
    "wildcard": {
       "dobdata": {
          "value": "*Nov09*"
       }
    }
  }
}

它解决了我的问题。希望这也能解决你的问题。

Answer 2

要获取月份日期= 11-09的结果，请使用以下查询。 dobdata的映射是

   border-left: 160px solid transparent;
    border-right: 160px solid transparent;
    width: 84%;

查询是：

"dobdata": {
        "type": "text",

        "fields": {
          "keyword": {
            "type": "keyword",
            "ignore_above": 256
          }
        }
      }

同样使用多字段映射而不是_raw字段请参阅here。

@K Sathish所以你使用elasticsearch 2.x？日期的字符串类型不那么舒适。我建议您在日期类型中更改字符串中的数据类型，这样您也可以获得范围查询。在日期类型中更改后，您可以通过以下方式在弹性2.x中进行查询：

{
  "query": {
    "filtered": {
      "filter": {
        "script": {
          "script": "doc.dobdata.date.monthOfYear == 11 && doc.dobdata.date.dayOfMonth == 9"
        }
      }
    }
  }
}

Elasticsearch在匹配查询中提供了不必要的记录
