Why doesn't Parenthesis \) Filter

I’m trying to filter using REGEX:

%title% MATCHES \s\(Radio\)$

To find: One Of These Days (Radio)

But it also finds things that aren’t even close, like:

Opal (Four Tet Remix)
Oops Up (Deejayovi Redrum)One
Week (Super Short Edit)

Try
%title% MATCHES "\s\(Radio\)$"

From the documentation

  • If <field> in HAS/IS/GREATER/LESS/EQUAL/MATCHES contains $ or % it should be enclosed in double quotation marks and will be treated as a format string instead of a tag field name.

Ahh, the old documentation. Why didn’t I think of that? Thank you.
