Normally Shopify only lets you filter by up to 3 product tags. It doesn’t offer any sort of boolean options, or the ability to filter anything else. There’s not much you can do about that. It is just what Shopify’s search does. Unfortunately, something like a single slider selector (greater than X AND less than Y) would occupy 2 of your 3 slots, even if it could do the greater/less than operator.
There’s also the performance. Each search filter is a new page load, or if using ajax, a new page load and yanking the content out of the page.
Ajax can also cause problems with back buttons and bookmarks, or sharing.
Roswell Studios has a solution to this, offering any number of complex filter operators with
a single local page load. Please contact us if you’d like us to set up your Shopify site, or to have this technology inserted into your existing Shopify site.
