Including dynamic templates for the elastic index

Elastic Stack Elasticsearch
1

Hello everyone,

I have an elastic index with the mappings set to strict except for one field which is dynamic. I would also like to set the mapping of the dynamic field using dynamic templates

PUT trial
{
   "mappings": {
      "dynamic": "strict",
      "properties": {
         "field1": {
            "type": "nested",
            "properties": {
               "display": {
                  "type": "keyword",
                  "index": "true"
               }
            }
         },
         "customFields": {
            "dynamic": true,
            "properties": {}
         }
      },
      "dynamic_templates": [
         {
            "customFields": {
               "match": "customFields",
               "mapping": {
                  "type": "text",
                  "index": "true"
               }
            }
         }
      ]
   }
}

Once I try to index the data in this index, it looks like the dynamic template is not applied

 "customFields": { - 
          "dynamic": "true",
          "properties": { - 
            "countries": { - 
              "type": "text",
              "fields": { - 
                "keyword": { - 
                  "type": "keyword",
                  "ignore_above": 256
                }
              }
            } 
         }
       }

I am missing something in here, but cannot find out what. Many thanks!

You cannot mix strict and dynamic like that sorry to say.

Thanks @warkolm for your inputs. So I guess the only way is to use the default mapping for dynamic field, i.e, allow the customFields to be indexed as both text and keyword.

Yep.
