ElasticsearchIllegalArgumentException [suggester [completion]需要设置上下文]

Question

我使用Elastic Search为名为people的索引实现自动提示字段：

字段person_name_suggest -

的映射如下所示

person_name_suggest: {
  type: "completion",
  analyzer: "simple",
  payloads: true,
  preserve_separators: true,
  preserve_position_increments: true,
  max_input_length: 50,
  context: {
    office_scope: {
     type: "category",
     path: "office_scope",
     default: [
       "0"
     ]
   }
  }
},

我需要弹性搜索的请求如下：

{ 
 "suggest":{
  "suggestions":{
    "text":"M","
    completion":{
     "field":"person_name_suggest",
     "context":890,
     "size":10
    }
   }
 }
}

我收到以下错误 - "error": "SearchPhaseExecutionException[Failed to execute phase [query], all shards failed; shardFailures {[OsbgjmewT569a-7ZoNCMtg][people_2016_10_29][0]: SearchParseException[[people_2016_10_29][0]: from[-1],size[-1]: Parse Failure [Failed to parse source [{"suggest":{"suggestions":{"text":"M","completion":{"field":"person_name_suggest","context":890,"size":10}}}}]]]; nested: ElasticsearchIllegalArgumentException[suggester [completion] requires context to be setup]; }

从我所看到的情况来看，我已将完成建议设置正确。

有人能指出我正确的方向吗？

正在使用的ElasticSearch版本为1.6

查询中存在语法错误。您必须指定上下文的名称

试试这个

{ 
 "suggest":{
  "suggestions":{
    "text":"M","
    completion":{
     "field":"person_name_suggest",
     "context":{"office_scope":890},
     "size":10
    }
   }
 }
}
