Searchanise Search & Filter

This app is fantastic. Much better than the out-of-the-box theme filters, and the search is great too. The configuration is powerful, allowing you to do pretty much anything you would want to, but the defaults are great too. You can also add custom CSS if you need to. The main thing about this app, is that the team behind it is awesome! Their support went completely above and beyond to help me figure out little things I had trouble with and helped me do a customization. All-star...def recommend!
