Hello.  
I want to make an index template for a document which has over 1000 fileds.  
But, I can't understand how to set a valid type for each field because making such template is too terrible...  
Can I make an index template which has a vague filed name?  
For example, the field name is "\*-date".  
In this case, I want to set the type, "timedate" for the field.

Best,

You could try something like [https://www.elastic.co/guide/en/elasticsearch/reference/6.5/dynamic-templates.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.5/dynamic-templates.html)

But it'll likely never be 100% perfect due to the size of the index you're dealing with.

Thank you for your reply!  
I understantd using dynamic template mapping is better.
