Smart Search & Filter

Filters work well.
Support is second to none.
If you're looking for a filter solution definitely give this app a go.

The app already worked well out of the box, with a clean basic design and not too many compatibility problems with my theme, but there were quite some things that needed to be adjusted.
Luckily the support is probably the best I've ever encountered after trying many filter apps, and they managed to fulfill every request I had very fast with clear, to the point communication. For example, I wanted the filter button to be sticky on the mobile version of the store, and they made it for my without extra charge. Now the filters display smoothly and clearly on my website, greatly improving user friendliness, while giving me detailed statistics about what my visitors are lookign for.
THE APP AND SUPPORT IS AMAZING, TRY IT OUT.

Great experience implementing this to our store. The customer service individuals were always extremely helpful and replied in a timely manner. Thank you Julia and Barb, you were both awesome and cleared up every question I had! This app gives our store the new look that we want and adds great functionality for our customers. I would highly recommend this app.

This Search & Filter app is very good. Mezereon kindly installed it on our 3rd party theme - we were so impressed with the team, we had some customisations done (which we paid for). The app itself is excellent - we have come across some user issues but the support team have always replied fast to solve our query. For example, we might sometimes forget how to do something and a quick email to Mezereon helps us solve the problem. The speed of the search suggestions and collection/search pages is lightning fast. You can adjust search results based on your preference, boost or demote products and so on. We have only scratched the surface with the curation lists, filters, synonyms and so on. Our team are looking at how we can better utilise the features to improve our user experience & customer expectations. Overall it's miles better than the default search from Shopify and specifically was a right fit compared to all the search engines we tried (we tried mostly ALL of them!).

This is a powerful app and the customer service was great. My previous theme was set up to use tags to filter with an "_" (i.e., size_8x10, size_11x14) and they helped me quickly integrate so I didn't have to revise thousands of items.
