Scenario:
There is a Ticket_Gallery control that uses Dataverse Table.
Here is one record from it.

What I am trying to do is to filter the galley by searching all columns by keyword that I type into TextInput. And data has to match a keyword in any part of the string (text). What should I do to find a match in lookup columns?
What I think I am looking for is something like a Search() function. But unfortunatelly Search doesn't work with Lookup columns as far as I know from Powerapps Docs.
Let me know if I need to clarify more details.
Any workarounds or solution/suggestions?
