Question

我正在尝试查询我的ES，这是我的数据，你可以在意义上运行它，它创建索引fst并用4个项填充它。然后你可以看到它返回错误的结果编号我只想要一个结果，就像这样。

PUT fst/objects/ggg
{
    "frameAttributes": {
    "identities": [
     { "_id": "DSC00263",   "_score": 0.655822},
     { "_id": "DSC00262",   "_score": 0.59957 },
     { "_id": "DSC00244",   "_score": 0.220819},
     { "_id": "DSC00300",   "_score": 0.191191},
     {"_id": "DSC00276",    "_score": 0.124561}

    ]
    }
}
PUT fst/objects/ffffff
 {
   "frameAttributes": {
    "identities": [
         {"_id": "DSC00222","_score": 0.191009},
         {"_id": "DSC00261","_score": 0.146157},
         {"_id": "DSC00329","_score": 0.14518},
         {"_id": "DSC00225","_score": 0.12622},
         {"_id": "DSC00295","_score": 0.12396}
      ]
   }

}
PUT fst/objects/aaaa
 {
   "frameAttributes": {
       "identities": [
         {"_id": "DSC00229","_score": 0.223149},
         {"_id": "DSC00240","_score": 0.178388},
         {"_id": "DSC00228","_score": 0.173769},
         {"_id": "DSC00257","_score": 0.166746},
         {"_id": "DSC00226","_score": 0.153071}
      ]
   }
 }
put fst/objects/abcdef
{
   "frameAttributes": {
     "identities": [
         { "_id": "DSC00262","_score": 0.427957},
         {"_id": "DSC00263","_score": 0.408772},
         {"_id": "DSC00282","_score": 0.284546 },
         { "_id": "DSC00283","_score": 0.191374},
         {"_id": "DSC00299", "_score": 0.165478}
      ]
   }
}

我的查询应该只返回一个结果

get fst/_search
{
    "query": {
        "term": {
           "frameAttributes.identities._id": {
              "value": "DSC00229"
           }
        }
    }
}

Answer 1

您必须将所需字段设置为not_analyzed。在您的情况下，该字段为_id。您可以在创建索引时执行此操作。例如：

PUT /gb/_mapping/tweet
{
  "properties" : {
    "tag" : {
      "type" :    "string",
      "index":    "not_analyzed"
    }
  }
}

Answer 2

花了一段时间但我学到了一些新的弹性搜索并不像你想要创建一个名为_id的字段。我将其更改为personId，现在它正常工作。

全部谢谢：）

弹性搜索查询词返回所有数据
