Complex search term doesn't work

I’m trying to search for a hashtag with a geographical location. (#hashtag near:”london”). It works fine on twitter search but doesn’t seem to work (return any results) in the widget. Anything I can do to fix this?

Adding two terms (#hashtag london) seems to pull results for either just fine btw.

Thanks!
