From the curseforge comments:

Can we please get a search function to filter our rules? I have a lot of rules setup and trying to find certain ones is a real pain if I can't keyword search the list. Thanks!

How would this work? What would you type and what would it find?

This wasn't my suggestion, but I can see a use-case for it. I'm currently sitting at 55 rules. I have rules for each Class, each Race, a couple of Professions and a handful of Class Specs. It would be neat if I could search the word "Class" and it would filter the list down to only the rules containing a "Class : something" condition; similarly with "Race". Perhaps I search "Mage" and it returns my "Class : Mage" as well as my "Specialization : Mage : Arcane", "Specialization : Mage : Fire", etc. If I search "Profession", it returns my rules containing "Advanced : profession:something"

This would allow me to quickly find a rule if I need to edit it, or allow me to confirm I didn't miss any classes/races, etc. when creating all the rules.
