Search for multiple users' tweets


In my iphone app, when I search for a single user’s tweets I get the results I expect. However when I try to combine multiple users, I get zero tweets. For example- OR from:BikeLeague OR from:peopleforbikes OR from:bikesbelong
This worked fine with version 1, but with 1.1, I don’t get anything back. What am I doing wrong? Thanks.
