These are capturing groups. $0 is the whole string found, $1 is the first capturing group.(for what is the $0 or $1)?
It should work, but it's not recommended as if $replace rule is applied everything else ignored.Sadly generic rules aren't working
/$replace=/Rule/Beer/ -- filter editor is complaining sadly.
Maybe that's because google is using query string in some places?
$replace rules are literally a last resort and I don't think we should not make using them a common practice.Also there should be an additional option to not disabling other rules when replacing text.
I got your point. Still I think using $replace rules for this is an overkill.Sometimes the user wants to replace some annoying text like "Posted with Tapatalk ..." in forum posts and when it is used, other ads may be displayed.
