Syntax to filter REST API

Hi There,
what is the syntax to filter the REST API for text?
I can use the filter for a straight comparison, like selecting the entity with the id 5 like so:

filter={"id": 5}

but lets say filter by name does not work.

filter={"name": "%tom%"}

Is there any documentation about the proper syntax or are fulltext searches not supported (yet?)
Many thanks!

Please try {"name":{"$includes":"tom"}

Refer to https://docs.nocobase.com/api/database/operators#includes

Thank you very much, didn’t see that in the docs.
Works like a charme.
