Elasticsearch自动生成_id以连字符开头不可搜索

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作为第一个字符自动生成时，它不能被搜索。我应该在这个领域设置一个映射吗？（到目前为止我对这个整个指数无映射）Elasticsearch自动生成_id以连字符开头不可搜索

参见下面的例子中，我得到了通过让http://localhost:9200/cazv/issue/_search?pretty=true&q=*:*

..., { 
     "_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"} 
    } 
, ...

当我试图找到第一个问题，使用http://localhost:9200/cazv/issue/_search?pretty=true&q=_id:vvQWnjYqSU2GJ4hrRnOBXw

我没问题得到

{ 
    "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"} 
    } ] 
    } 
}

但是当我尝试通过获取http://localhost:9200/cazv/issue/_search?pretty=true&q=_id:-yTCu-HxSkOhwDOp4JVblg

拿到第二个问题

我得到一个错误，而不是：

通过查询报价解决： 'HTTP：//本地主机： 9200/cazv/issue/_search？pretty = true＆q = _id：“ - yTCu-HxSkOhwDOp4JVblg”' 也许编码双引号会更好，所以这个URL看起来像这样： 'http：// localhost：9200/cazv /问题/ _search漂亮=真＆q = _id：％22 yTCu-HxSkOhwDOp4JVblg％22' – Beyboy 2014-11-25 09:59:15

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 - 它让人困惑。你可能会想提出引号术语或只使用一个术语查询的id字段或只是把它的URL /index/type/id

我也有类似的问题，所以我使用的映射来超越我productId使用_id。你的情况设置_id到volumeId，但我不知道你的volumeId是否是唯一的。

映射：

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

映射之后：

..., { 
    "_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"} 
}

我希望帮助。
