search, repeatedly re-enable soft keyboard for no reason

Search starts after user typed in a few characters, that is good.

Because you don't actually have to press the search button to start a search many users won't ever press this button. They may hide the keyboard by pressing the back button or selecting an app from the list to view its details, in both cases the keyboard is hidden.

Trouble is, whenever hitting back after viewing details of an app the keyboard is re-enabled. This is very frustrating. If you look at the details of 15 apps from the list of search results.. the soft keyboard will come into your way 15 times.

Meanwhile, I found out that this behavior does not happen if you actually press the search button but this is not obvious and most of the time unwanted.

I would propose, that once the keyboard is hidden either explicitly (back key) or implicitly by selecting an app from the list to view the app details, it should be only re-enabled when the user hits the search text field thus refocusing it.
