What is the intended behaviour of GET search?


So I’m currently trying to use the call to GET search/tweets.
I’m wondering what is the intended behavior of the request when
both query string(s) and coordinates are supplied.

The I wish for it to work is to grab from the geolocation specified
(and within the radius), tweets from that area which are then filtered by
the query term(s). However, it seems as if what is happening is that
I’m being returned tweets that either contain the query string OR are
in the location, thus not being specific enough for my needs.

Can anyone advise or clarify?
