How can i surch by tag?

Choose one manga for example:
You're My Loveprize In Viewfinder, then see the right screen just below the "These lists have this manga" there's "Top tags", you can click any tags you want. Hope that'll help.

Maybe too late..

example: http://www.mangago.me/tag/yaoi

for spaced tags, use "+" or "%20" as separation
