dynamic - 为嵌套文档定义动态 not_analyzed 字段

Question

我有一个如下所示的文档，“tags”字段是一个嵌套文档，我想将标签文档的所有子字段设置为index = not_analyzed。问题是标签中的字段是动态的。任何标签都可能。那么我如何为此定义动态映射。

{
 strong text'level': 'info',
 'tags': {
  'content': u'Nov  6 11:07:10 ja10 Keepalived_healthcheckers: Adding service [172.16.08.105:80] to VS [172.16.1.21:80]',

  'upgrade': 'no upgrade configuration for this alert'
 },
 'timestamp': 1383707282.500464
}

我认为你可以使用dynamic templates为了这。例如，以下 shell 脚本使用在索引字段 tags.* 时设置的 dynamic template 创建 dynamic_mapping_test 索引，映射设置为 type:string 和 index:not_analyzed。

echo "Delete dynamic_mapping_test"
curl -s -X DELETE http://localhost:9200/dynamic_mapping_test?pretty ; echo ""

echo "Create dynamic_mapping_test with nested tags and dynamic_template"
curl -s -X POST http://localhost:9200/dynamic_mapping_test?pretty -d '{
  "mappings": {
    "document": {
      "dynamic_templates": [
        {
          "string_template": {
            "path_match": "tags.*",
            "mapping": {
              "type": "string",
              "index": "not_analyzed"
            }
          }
        }
      ],
      "properties": {
        "tags": {
          "type": "nested"
        }
      }
    }
  }
}' ; echo ""


echo "Display mapping"
curl -s "http://localhost:9200/dynamic_mapping_test/_mapping?pretty" ; echo ""

echo "Index document with new property tags.content"
curl -s -X POST "http://localhost:9200/dynamic_mapping_test/document?pretty" -d '{
  "tags": {
    "content": "this CONTENT should not be analyzed"
  }
}' ; echo ""

echo "Refresh index"
curl -s -X POST "http://localhost:9200/dynamic_mapping_test/_refresh"

echo "Display mapping again"
curl -s "http://localhost:9200/dynamic_mapping_test/_mapping?pretty" ; echo ""

echo "Index document with new property tags.title"
curl -s -X POST "http://localhost:9200/dynamic_mapping_test/document?pretty" -d '{
  "tags": {
    "title": "this TITLE should not be analyzed"
  }
}' ; echo ""

echo "Refresh index"
curl -s -X POST "http://localhost:9200/dynamic_mapping_test/_refresh"; echo ""

echo "Display mapping again"
curl -s "http://localhost:9200/dynamic_mapping_test/_mapping?pretty" ; echo ""
