设置search_analyzer时，必须在字段[文件名]上设置分析器。 弹性搜索误差

Question

在为我的elasticsearch index_analyzer设置mappings时收到以下错误消息

请在下面找到错误消息

{
  "error": {
    "root_cause": [
      {
        "type": "mapper_parsing_exception",
        "reason": "analyzer on field [filename] must be set when search_analyzer is set"
      }
    ],
    "type": "mapper_parsing_exception",
    "reason": "Failed to parse mapping [doc]: analyzer on field [filename] must be set when search_analyzer is set",
    "caused_by": {
      "type": "mapper_parsing_exception",
      "reason": "analyzer on field [filename] must be set when search_analyzer is set"
    }
  },
  "status": 400
}

请找到我尝试过的映射详细信息

PUT /documents_test8

   "settings" : {
      "analysis" : {
         "analyzer" : {
            "filename_search" : {

               "filter" : ["lowercase"]
            },
            "filename_index" : {
               "tokenizer" : "filename",

         },

               "search_analyzer" : "filename_search",
               "index_analyzer" : "filename_index"
            }
         }
      }
   }
}

index_analyzer属性不再存在，您需要使用analyzer

"mappings" : {
  "doc" : {
     "properties" : {
        "filename" : {
           "type" : "text",
           "search_analyzer" : "filename_search",
           "analyzer" : "filename_index"              <-- change this
        }
     }
  }
}
