elasticsearch - 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" 
            }
        }
}

但是它给出了一个错误:

{
  "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
}

我也试图重新创建索引
通过:

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

但是我得到了:

{
 "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
 }

我也尝试将_type更改为关键字，但仍然无法正常工作。
基本上，我想搜索字符串的完全匹配，为此，我指的是:

Answer 1

该文档页面来自Elasticsearch 2.X版(请参阅页面顶部)，并且不再适用于现代版本的Elasticsearch。

您得到的错误是因为“index”现在仅接受true或false，并指示是否对属性进行了索引-由于您要通过该属性进行搜索，因此您希望它成为true(默认值) 。

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

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