Combine exact phrase and hashtag search



I want to use the twitter API to search for an exact phrase AND a hashtag. I can get the API to search using one or the other but not both combined.

The same search on the twitter website returns results but with the API draws a blank. For example:'concentrating%20on%20the%20league'%26%23facup&src=typd

This returns plenty of results but cannot replicate via the API.

The search query am attempting is"concentrating%20on%20the%20league"%26%23facup but is returning no results.

Any thoughts on the above appreciated
