date - 如何在Elasticsearch映射中从 “_all”中排除所有数字和日期

Question

我想从elasticsearch的“_all”字段中删除所有数字和日期。这样可以减小尺寸并提高性能。我以为可以通过使用dynamic_templates完成此操作，但我无法使其正常工作。

映射是这样的(为了简单起见，仅用于数字):

{
 "mappings" : {
  "log" : {
   "dynamic_templates" : [{
     "_Excl_numbers" : {
      "match" : "*",
      "match_mapping_type" : "long",
      "mapping" : {
       "type" : "long"
      },
      "include_in_all" : false
     }
    }
   ]
  }
 }
}

我使用的测试数据(索引类型=“log”):

POST: http://{{URL}}/{{TEST_INDEX}}/_bulk
{"index":{"_type" : "log", "_id" : "2" } }
{"level_array":{"id":2,"ingestDate":null},"path":"rvh","group":"U-17"}
{"index":{"_type" : "log", "_id" : "3" } }
{"level_array":{"id":3,"ingestDate":"2011-08-04"},"group":"U-12"}
{"index":{"_type" : "log", "_id" : "4" } }
{"level_array":{"id":4,"ingestDate":"2011-08-04T10:00:00"},"path":["rvh","fcl"],"group":"U-17"}
{"index":{"_type" : "log", "_id" : "5" } }
{"level_array":[{"id":5,"ingestDate":"2011-09-07"},{"id":5,"ingestDate":"2011-02-05"}],"titel":"0125-DCU-INTR-TST-17"}

现在，该查询应该没有任何结果，但是我这样做了:

{
 "_source" : true,
 "query" : {
  "simple_query_string" : {
   "query" : "2",
   "analyze_wildcard" : true,
   "default_operator" : "AND"
  }
 }
}

那么，如何更改映射以从“_all”字段中排除所有数字(以及日期， bool(boolean) 值等)？

ElasticSearch版本是2.3.4

您只是将include_in_all放在了错误的级别。它应该是:

  "dynamic_templates": [
    {
      "_Excl_numbers": {
        "match": "*",
        "match_mapping_type": "long",
        "mapping": {
          "type": "long",
          "include_in_all": false
        }
      }
    }
  ]
