Shopify Search & Discovery

I love Jeremec 16" deep wave wigs and bulk braids, and they’re amazing! The wigs are soft, natural-looking, and offer great versatility. The bundles are thick, long-lasting, and perfect for adding volume, while the bulk braids are tangle-free and easy to install. Overall, the quality is fantastic and a must-try for anyone looking to upgrade their hairstyle!

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.

The Availability filter does not work. For whatever reason, it displays the total product count instead of the inventory count AND it's not even recognizing variants, so it's completely useless. Outside of this app, the inventory counter is displaying correctly on the product page so obviously the problem is with this app. This availability filter code is no good.
Hand coded filters used to work on Shopify but because of this newfangled junk, they don't anymore. This app has to be enabled for ANY filter to display - so you can get hand coded filters to show up, but they will only display error msgs, because Shopify 2.0 only accepts filter content from apps. I'm not a fan of chunking out useful features into a bunch of add-ons.

UPDATE: found a source of incompatibility between this app and Shopify 2.0 free themes V 15.0. In facets.liquid, ALL filters print value.count. Value count = the number of product LISTINGS. This is only relevant to count by category, like qty of products that are t-shirts, qty of products that are hats, etc. This is entirely useless for inventory. I've managed to decouple the Availability filter from this irrelevant nonsense by using {%- if value.label contains "stock" -%}. However I've tried literally THOUSANDS of call combinations, logic, and assigns within this if clause and cannot get it to print the actual in stock inventory. I've been able to get it to print a fixed qty, or a (0), or a total product listings count, or even the total value of products in the cart. Anything but the inventory qty seems to work here. Please reply with the exact code needed for this to function properly. Thanks!!!!

UPDATE #2:
Thank you for responding but, that's honestly not an adequate solution whatsoever. As you pointed out, IT WILL NOT SUM, which means that will return a string of values that will read for example: "(4)(45)(9)(3)(1)(1)(3)(6)(2)(1)....etc." It could break the screen border with this nonsense. And it looks janky, which will bounce customers off the site instantly. AND your suggestion to do this as another layer of app bloat on the app sandwich is perfectly absurd.

Let me know when Shopify is ready to give serious support and tell me how to CODE a reasonable solution into facets.liquid and it's associated .js and .css theme files.

It's an embarrassing oversight on the part of Shopify that there is no availability filter that shows in stock goods vs out of stock goods (regardless if the out of stock can still be custom ordered). Site visitors should be able to easily filter products on this basis because it affects how quickly the product will be shipped. Is this really a condition Shopify wants it's sites to perform poorly on? Isn't that kind of contrary to the whole mission of good ui > good seo > good revenue?
You have a feature that is not working as advertised. Please fix it or tell me how I can fix it IN THE THEME FILES WITH CODE. Don't come at me with any more apps, alternatives, or substitutes. I assure you I am either already employing them or have tested them and found them inadequate.

UPDATE: Wait wait wait wait. So now I'm noticing that this app doesn't even use canonical URLS in the recommended products gallery! Are ya'll joking with this entire thing or what?

helpful, easy to navigate and make the customer search & discovery game easier.

Great app that is easy to install and simple to integrate and setup.
Only feature missing is a Buy Now or Add to Cart button for the products so that customers don't have to leave the main item page to simply buy an add on.
