Works quite well, except I was confused at first how to start the search - I wrote a search term and then tapped on the "user search" button and nothing happened, only later did I figure out one has to hit the "enter" button on the virtual keyboard. Two suggestions:

1. Rename the "enter" button to "search", I think some apps can do that (like the Nokia store app).

2. Possibly add a dedicated "search" button.

Or just ignore my dumb first try
