Possibility of grouping several tags with parentheses

E.g. a note about a chess game could be tagged like this: "(player/Jack_Jackson color/white) (player/Ben_Benson color/black)"

And, obviously, when two (or more) tags belonging to different parenthesized groups are highlighted in the sidebar (e.g. "player/Jack_Jackson" and "color/black"), then the note shouldn't be displayed.
