E.g. being able to search "tag1 AND NOT (tag2 OR tag3)"
searching complexity:medium

I know SQLite has great support for proximity searching, e.g. apple NEAR orange.  It would be great to be able to find closely occurring search terms.

Thanks for the idea. I'd suggest you post it as a separate request, because this one is about tag operations.. thanks!
