Hi André,
You need to create an database entity to store the filter's values.
This entity needs to be associated with the Administration.Account, so that when you refresh the page, you can retrieve your filters' record based on the current user (currently logged in user).
To make sure your filters' values are up to date, you need to commit the filter object upon clicking Search, for instance.
Let me know if this helps or if you need further assistance
Thank you João,
This gave me a cleary direction on where and how to start!
