title: Solr Geo based search
body: <p>We are starting to use Solr for a geographic based search engine. We provide a GPS location, and a radius and keyword. It is unclear to us if Solr first restricts the GPS location, then does a keyword search, or if it first does a keyword search and then reduces the results by filtering our results outside of the radius ... The first case would be preferable in our situation, as we have many data sets over all, but a small subset in a certain location, increasing the speed of the search.</p>
