[suggest]的映射定義具有不受支持的參數：[payloads：true]

我正在使用ElasticSearch文檔here使用Completion Suggestor的示例，但出現錯誤，說明payloads: true是不受支持的參數。除非文檔錯誤，哪些顯然是支持的？我有最新的Elasticsearch應用程序安裝（5.3.0）。[suggest]的映射定義具有不受支持的參數：[payloads：true]

這裏是我的捲毛：

curl -X PUT localhost:9200/search/pages/_mapping -d '{ 
"pages" : { 
    "properties": { 
     "title": { 
      "type" : "string" 
     }, 
     "suggest" : { 
      "type" : "completion", 
      "analyzer" : "simple", 
      "search_analyzer" : "simple", 
      "payloads" : true 
     } 
    } 
    } 
}';

和錯誤：

{ 
    "error" : { 
    "root_cause" : [ 
     { 
     "type" : "mapper_parsing_exception", 
     "reason" : "Mapping definition for [suggest] has unsupported parameters: [payloads : true]" 
     } 
    ], 
    "type" : "mapper_parsing_exception", 
    "reason" : "Mapping definition for [suggest] has unsupported parameters: [payloads : true]" 
    }, 
    "status" : 400 
}

對於5.3的文檔是不同的：https://www.elastic.co/guide/en/elasticsearch/reference/5.3/search-suggesters-completion.html#completion-suggester映射，並且不再有「有效載荷」。 –

@AndreiStefan哇，我現在不覺得愚蠢。閱讀這些新文檔，我沒有看到類似於有效載荷的任何內容。我需要爲建議添加額外的信息。有沒有辦法做到這一點？此外，如果你添加這個答案，我可以標記它是正確的，哈哈。 – l3fty

那麼，別人已經做了搜索，並發現github問題有關「有效載荷」的刪除。 –

的參數已經在ElasticSearch 5.3.0被刪除通過以下承諾：Remove payload option from completion suggester。下面是COMIT消息：

The payload option was introduced with the new completion 
suggester implementation in v5, as a stop gap solution 
to return additional metadata with suggestions. 

Now we can return associated documents with suggestions 
(#19536) through fetch phase using stored field (_source). 
The additional fetch phase ensures that we only fetch 
the _source for the global top-N suggestions instead of 
fetching _source of top results for each shard.
