Elasticsearch自動生成_id以連字符開頭不可搜索

在ElasticSearch中，我有自動生成_id字段的文檔。我需要通過這個_id進行搜索。不幸的是，當_id作爲第一個字符自動生成時，它不能被搜索。我應該在這個領域設置一個映射嗎？（到目前爲止我對這個整個指數無映射）Elasticsearch自動生成_id以連字符開頭不可搜索

參見下面的例子中，我得到了通過讓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"} 
    } 
, ...

當我試圖找到第一個問題，使用http://localhost:9200/cazv/issue/_search?pretty=true&q=_id:vvQWnjYqSU2GJ4hrRnOBXw

我沒問題得到

{ 
    "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"} 
    } ] 
    } 
}

但是當我嘗試通過獲取http://localhost:9200/cazv/issue/_search?pretty=true&q=_id:-yTCu-HxSkOhwDOp4JVblg

拿到第二個問題

我得到一個錯誤，而不是：

通過查詢報價解決： 'HTTP：//本地主機： 9200/cazv/issue/_search？pretty = true＆q = _id：「 - yTCu-HxSkOhwDOp4JVblg」' 也許編碼雙引號會更好，所以這個URL看起來像這樣： 'http：// localhost：9200/cazv /問題/ _search漂亮=真＆q = _id：％22 yTCu-HxSkOhwDOp4JVblg％22' – Beyboy 2014-11-25 09:59:15

您正在使用查詢解析器，它將-解釋爲NOT前綴運算符，我個人認爲它是第二個 - 它讓人困惑。你可能會想提出引號術語或只使用一個術語查詢的id字段或只是把它的URL /index/type/id

我也有類似的問題，所以我使用的映射來超越我productId使用_id。你的情況設置_id到volumeId，但我不知道你的volumeId是否是唯一的。

映射：

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

映射之後：

..., { 
    "_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"} 
}

我希望幫助。
