The search in filters works in such a way that I always have to type the word I’m looking for in the right order, e.g. I’m looking for product1, but in the table the entry looks like group1_product1 and it will not be found.
This is a great pity, that is a must have feature.
Or is there a way to do that?
upd.: here someone has already asked that Type of search in fields used in filters (LIKE type)
