refine search with ranges
I'm making a classified site for cars. The Refine Search only gives you the option for selecting a slider or range for Radius and Price. I couldn't figure out how to add ranges for other Custom Fields such as Year or Mileage. For example, Refine Search to find cars with model year 1990-2000.
I found a plugin called "Advanced Search for Classipress" by Classipro, which allows me to make ranges for all of my necessary custom fields, but it doesn't have a Radius function like the default Refine Search.
Is there a way to make ranges possible in Refine Search? Or do you know of a way to make the Classipro plugin work with the Radius feature?
