Question

在ElasticSearch中，我有自动生成_id字段的文档。我需要通过这个_id进行搜索。不幸的是，当_id是以第一个字符作为自动生成时，无法搜索它。我应该在这个字段上设置映射吗？（到目前为止，我没有整个索引的映射）

请参阅以下通过GETting http://localhost:9200/cazv/issue/_search?pretty=true&q=*:*

获得的示例

..., {
      "_index" : "cazv",
      "_type" : "issue",
      "_id" : "vvQWnjYqSU2GJ4hrRnOBXw",
      "_score" : 1.0,
      "_source":{"volumeId": "At8YmsUdRqmqX-OUJKvdcQ",
"number": "No. 3"}
    }, {
      "_index" : "cazv",
      "_type" : "issue",
      "_id" : "-yTCu-HxSkOhwDOp4JVblg",
      "_score" : 1.0,
      "_source":{"volumeId": "Z97A5vG8TOSl7Bv0UlFGYg",
"number": "No. 1"}
    }
, ...

当我尝试查找第一个问题时，使用http://localhost:9200/cazv/issue/_search?pretty=true&q=_id:vvQWnjYqSU2GJ4hrRnOBXw

没问题

我得到了

{
  "took" : 137,
  "timed_out" : false,
  "_shards" : {
    "total" : 5,
    "successful" : 5,
    "failed" : 0
  },
  "hits" : {
    "total" : 1,
    "max_score" : 1.0,
    "hits" : [ {
      "_index" : "cazv",
      "_type" : "issue",
      "_id" : "vvQWnjYqSU2GJ4hrRnOBXw",
      "_score" : 1.0,
      "_source":{"volumeId": "At8YmsUdRqmqX-OUJKvdcQ",
"number": "No. 3"}
    } ]
  }
}

但是当我试图通过http://localhost:9200/cazv/issue/_search?pretty=true&q=_id:-yTCu-HxSkOhwDOp4JVblg

来解决第二个问题时

我收到了错误：

Answer 1

您正在使用查询解析器，它将-解释为NOT前缀运算符，我个人认为它是第二个 - 它让人感到困惑。您可能想在术语周围加上引号，或者只在id字段上使用术语查询，或者只是将其放在网址/index/type/id

中

我有类似的问题，所以我使用映射来覆盖我的ProductId的_id。在你的情况下，将_id设置为volumeId，但我不知道你的volumeId是否是唯一的。

映射：

{ 
 "issue" : {
  "_id" : {
    "path" : "volumeId"
  }
}

映射后：

..., {
  "_index" : "cazv",
  "_type" : "issue",
  "_id" : "At8YmsUdRqmqX-OUJKvdcQ",
  "_score" : 1.0,
  "_source":{"volumeId": "At8YmsUdRqmqX-OUJKvdcQ","number": "No. 3"}
}, {
  "_index" : "cazv",
  "_type" : "issue",
  "_id" : "Z97A5vG8TOSl7Bv0UlFGYg",
  "_score" : 1.0,
  "_source":{"volumeId": "Z97A5vG8TOSl7Bv0UlFGYg","number": "No. 1"}
}

我希望有所帮助。

从连字符开始的Elasticsearch自动生成_id是不可搜索的
