Only thing I've found on a boolean search method was
but it was more of a feature request. When looking at the help file, it said EN advanced search was "powerful". Ehh.
I guess a basic boolean search feature hasn't been implemented yet. So another +1 for this. Hopefully it comes out with the ability to use regex as well.
While we're requesting some features, I'd also like to suggest a way to fully close the gap in the differences between the Windows version and the Mac version.
Mac version seems way less advanced (no auto tagging, colored styles in sidebar) but has one feature that trumps the windows version which are TABS. Don't understand why the features between the two are so different.
