App Store not showing search results?

I've got an iPhone 4S which is running iOS 7.0.4. Whenever I go into the App Store and enter a search query and press 'enter', the screen just stays white and doesn't load anything. Or whenever I select to download something from the Top Charts, which display correctly, there's just a blue circle that doesn't stop spinning, the items do not download. Why is this happening please?

I own the same device with same ios. The fact is that this usually happens when the apple id is not registered properly or low network speed. To solve this just forget your Wi-Fi network if you are using and then re join it. The last way is to factory reset the device that will for sure(100%) solve your issue with the app store. And its a normmal problem there isn't anything to worry about it.
