If I use in Actions all possible fields, I use _ALL parameter (or %_all%).
But what shall I use in app's Filter Bar, if I need to search in all fields too,
e.g. in that ask:
%genre% MATCHES (?-i) (Folk)
What shall I use in the name %genre% for _ALL to search given word everywhere (from e.g. Genre to Composer)?
I tried %_ALL%, %ALL%, %all%, %_all%, all, ALL — nothing works.
So why I use in need all needed single fields with OR or AND, but that is not so much comfortable.
