@balepc Thanks for building the search feature! Are you able to help maintain this feature in the future?

[chadrem]

@balepc I tried out the code and it looks like it returns 20 apps max:

s = MarketBot::Play::Search.new('Facebook').update; puts s.result.length

I'd like to get this fixed before merging any search related pull requests. If you have time, please check out issue #38 (it has a link to a possible fix).
