Elastic search, no mappings with filters

In my project we have a feature that creates dynamic fields to the object so the field type can be for example text, float, object. and the user can change type for example I have a number field so the mapping in elastic will be float, and I changed the value to text it will cause an error in mapping.

or for example it was object then string, long story short mapping will cause issues, and if I ignored the mappings I will lose the ability to filter on these fields.

Is there a way in elastic that I can ignore the mapping and use filter?

Elasticsearch doesn't support change in type of fields. It is really important to define your Schema carefully, it is still possible to change the field type but you would need to reindex your data again. For more information about Reindex API you can check the ES official documentation here.

You can also try to implement your field mapping with suffix so each type of your field would have its own field. For example if you have a field name User and your client specified it as long you can store it as user_long and map it as long and if the client change the type later on in the application to string you can create new field user_text and map it as a text. Keep in mind with this approach you might need to convert your data but you won't need reindexing.
