Shopify Search & Discovery

app does not actually filter sizes, i have tried everything and it still does not work. sadly i have to go back to paying for an app which can filter properly

Not suitable for large shops. 200 filter values are possible, but only 100 are displayed. I don't understand why. Conclusion: a shop with more than 100 brands, for example, will not be able to use the filter effectively.

Addendum: Maybe the product is called A8000, a search for 8000 will not find this product. Such a search is completely useless.

The app has a bug that doesn't work with recommended products on product pages.

Lot's of errors in the search. Not organized if you have a lot of products. Messy looking. You have to scroll & scroll to view the searches. Does not work with keywords.

doesn't work with size variants

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?

Update: The only support received by now has been the reply here, yet is a very generic answer, which doesn't resolve the issue.

To their reply: I know where to find the "Out of Stock Products" setting, which is set to show only products "In Stock" by default; yet, ALL (In+Out of Stock) products show up. The issue persists, and worst, if I delete the app, it won't go away from my website. So I cannot move on to another reliable option in the market.

Original Review: I like the app, but I give it a 2 star rating as I couldn't get any support to ask some relatively basic questions about different features that are not working (like the setting for "Out Of Stock Products" which I want to show "Not At All", yet, they show on the site.)

They replied: "The "Out of Stock Products" setting is under the "Search relevance" section of the app settings. It controls how out of stock products and variants are handled in search results. This setting does not affect how out of stock products and variants are handled on Collection pages. You can read a bit more about this setting in the public Help docs at https://help.shopify.com/en/manual/online-store/search-and-discovery/search#search-result-types"

Not able to auto-collapse filters. Not able to set different filter sets for different collections. Not able to use sliders for number values other than price.

Shopify is a great concept

How can Shopify have a native search app that doesn't allow customers to search for items via their SKU?? All of our products have specific SKU names that are intrinsic for liaising with customers. I now have 3 Shopify stores that are causing so much frustration - a massive problem that could be solved with one simple fix. Shopify, surely its time to fix this?!
