Hi I'm having indices being sent dynamically to my project.

When indices are being pushed , fields are mapped dynamically.  
Due to this mappings are different everytime.  
For example for 1 index , created date field is formatted as text and another it is formatted as date.

We cannot change mapping for existing fields.  
Is there a way to handle existing indices & also before pushing indices.  
And for dynamic mapping can we do this before pushing by mapping templates ?

I think you had to use explicit mappings. From now what you can do is reindex the index or add multi field to the fields.
