更改elasticsearch映射

Question

我正在尝试使用以下代码更改映射：

PUT /in_test/_mapping/keyword
{
 "properties" : {
            "term" : {
                "type" : "text",
                "index" : "not_analyzed" 
            }
        }
}

但它给出了一个错误：

{
  "error": {
"root_cause": [
  {
    "type": "remote_transport_exception",
    "reason": "[tiebreaker-0000000000][172.17.0.24:19555][indices:admin/mapping/put]"
  }
],
"type": "illegal_argument_exception",
"reason": "Could not convert [term.index] to boolean",
"caused_by": {
  "type": "illegal_argument_exception",
  "reason": "Failed to parse value [not_analyzed] as only [true] or [false] are allowed."
}
},
"status": 400
}

我还尝试通过以下方式重新创建索引：

PUT /in_test
 {
"mappings" : {
    "keyword" : {
        "properties" : {
            "term" : {
                "type" : "text",
                "index" : "not_analyzed" 
            }
        }
    }
}
}

但我得到了：

{
 "error": {
"root_cause": [
  {
    "type": "mapper_parsing_exception",
    "reason": "Failed to parse mapping [keyword]: Could not convert [term.index] to boolean"
  }
],
"type": "mapper_parsing_exception",
"reason": "Failed to parse mapping [keyword]: Could not convert [term.index] to boolean",
"caused_by": {
  "type": "illegal_argument_exception",
  "reason": "Could not convert [term.index] to boolean",
  "caused_by": {
    "type": "illegal_argument_exception",
    "reason": "Failed to parse value [not_analyzed] as only [true] or [false] are allowed."
  }
}
 },
 "status": 400
 }

我还尝试将 _type 更改为关键字，但它仍然不起作用。基本上，我想搜索字符串的精确匹配，为此我指的是：

Answer 1

该文档页面来自 Elasticsearch 版本 2.X（请参阅页面顶部），对于现代版本的 Elasticsearch 来说不再正确。

您收到的错误是因为“index”现在只接受true或false，并且指的是该属性是否完全被索引 - 由于您正在按此属性进行搜索，因此您希望它是true（默认值）。

相反，尝试将类型设置为“关键字”，它不会被标记化。https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-keyword-analyzer.html#_definition_5

PUT /in_test
{
"mappings" : {
    "keyword" : {
        "properties" : {
            "term" : {
                "type" : "keyword"
            }
        }
     }
}
}
