Hi again Alex,
I still have problems with the Ajax filtering. This time I noticed that when I want to search a listing by Make, it won't search for some makes correctly.
For example, here: www.elicesmotoracing.com/motos If you search for the makes: Harley Davidson, MV Agusta, MH Motor Hispania or Yamoto nothing appears but if you search it manually using the pagination you can find that the listings of those makes appear.
What could it be?
