Searching Champions by Runeterra's Region/Faction

I just tried to see what would happen if I typed in 'Freljord' in the search bar and have the Freljord champions appear, nothing happened =/ I be a sad panda now =( BUT I think it would be cool if the search engine for champions can be searched by faction / region of Runeterra, so typing in Freljord, Noxus, Demacia, Bildgewater [I don't know how to spell this, might be right?], Shurima, Ionia, Zhan [I think this is right], Piltover, etc. Will bring up those champions.

I personally think this would be a really cool thing to add to the game to find champions by their region/faction/etc, plus this allows the easy use of seeing how many champions are in each region.
