Users search multiple terms



I’m trying to search for users based on multiple terms, but I seem to get back two different result sets when using the twitter search and the api search. For example the query ‘GBGroup near%3A"london" within%3A15mi’ returns the one expected result on the twitter site search, however the same query through the api (via the twitter console) returns a list of users, I believe it’s only using the first word ‘GBGroup’ for the search. Is the api query in the wrong format or are different rules applied to the api?
