how to target Google Play Search? It is very annoying, that almost everytime I search for Apps (i.e. Go SMS, Handcent SMS, Viber, etc...)

in the results always show up i.e. "Go SMS silver theme", "Viber Smiles"....

so, the actual app i am searching for, never shows up in the top results..
what is the solution to this annoying cases..
Found the reason. this happens on the apps, that are not supported to my country, for unknown reason I have no idea. I've installed them manually from their site, by downloading APK.
