Requested feature overview description.
Simply put, regular expressions are cool. I wanna use them when searching for note vandalism and/or specific phrases.
Why would it be useful?
I have a handful of links on my profile that are made with the express purpose of finding cases of note vandalism. Certain users seem to think it's a great idea to just completely replace English translations with other languages, so every so often I've gotta dive in to make sure that it isn't happening again. I could either manually generate several thousand search queries to capture every possible character that appears outside of standard English, or I could just use character ranges available in regular expressions to do that.
What part(s) of the site page(s) are affected?
The Note Search page, and possibly every other page under the Notes link in the header.
