Make / model search via Refine Search block doesn't work during first try
Steps to reproduce the bug:
1) go to any page with the Refine Search block (for example, http://demos.subrion.com/autos/autos/ )
2) choose Make and model of car that presents on website (for example, MAZDA CX-7 )
3) there will be no results found (screenshot attached).
BUT if you change Make and model to another car that presents on website you'll get results.
