I'm wanting to map all fields in my indices to a String. I understand that you do this with a mapping but I'm having trouble constructing the correct structure. If I don't, there will be collisions with a field "Code" being either an integer or string with my given input. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hello Grayson , You can use \_default [http://www.elastic.co/guide/en/elasticsearch/reference/1.x/index-modules-mapper.html#\_default\_mapping](http://www.elastic.co/guide/en/elasticsearch/reference/1.x/index-modules-mapper.html#_default_mapping) \_ [http://www.elastic.co/guide/en/elasticsearch/reference/1.x/index-modules-mapper.html#\_default\_mapping](http://www.elastic.co/guide/en/elasticsearch/reference/1.x/index-modules-mapper.html#_default_mapping) to mark all types under a type. Then you can use dynamic field template [http://www.elastic.co/guide/en/elasticsearch/guide/master/custom-dynamic-mapping.html#dynamic-templates](http://www.elastic.co/guide/en/elasticsearch/guide/master/custom-dynamic-mapping.html#dynamic-templates) to impose this rule. In your case you can use match\_mapping\_type to identify all numbers and impose string mapping. Or even apply to \* pattern should also work , with the top being more accurate.
