Zelouf Fabrics review for Shopify Search & Discovery

The search app is good, but there's lacking features. If you have a store with more than 5000 items, the filter doesn't show and there's no way to filter a collection by product count. Out of stock items are hidden in search, but forget about it if someone is browsing products. Customize filters with metadata works fairly well, but for some reason adding thousands of data points to group makes the app not show all the data to group it in the app, but shows it to the customer on the website ungrouped.
