Your example box is very small and somewhere in the middle of Minsk: http://www.openstreetmap.org/?box=yes&bbox=27.538543,53.912676,27.538651,53.912563 Are you sure you copied the right example?

Sorry, you are absolutely right, this is the right example below:

http://nominatim.openstreetmap.org/search?q=pub&limit=20&format=json&email=info[at]galileo-app.com&bounded=1&viewbox=-2.249724,53.468505,-2.249616,53.468409

Your viewbox is still tiny: http://www.openstreetmap.org/?box=yes&bbox=-2.249724,53.468505,-2.249616,53.468409 and does not contain any pubs or bars, so the empty answer is completely correct.

The behaviour of the bounded parameter got fixed lately. If bounded=1 is given, Nominatim will really only return objects within that box. Remove the bounded parameter if you want the old behaviour back.
