not sure if I missed something but when I was using Chrome I did not see a search bar for searching games by name. Only a filter by category. If you don't have one, you should really consider adding one.
Retested on my PC. It appears now but I'm not sure how well your search is working. I searched "Rune Master" expecting to see one of my games appear and I seen two games with Rune and Master in their name. The rest did not even resemble anything related and my game never appeared. So not sure what's going on with that ...
