Filtering products from collection by tag with Storefront API

[lukebennett]

I'm building a Shopify store using the Storefront API.
I noticed that in the most recent version of the API (2023-01) there is now support to filter products in a collection by tag. I need to filter by tag so I can show ladies or mens products, so this feature is very useful for me.
However it doesn't seem to be working.

When I run this query:

query {
  collection(handle: "greg-norman") {
    title
    products(first: 30, filters: { tag: "Mens" }) {
      nodes {
        title
        vendor
        tags
      }
    }
  }
}

I get back this data:

{
  "data": {
    "collection": {
      "title": "Greg Norman",
      "products": {
        "nodes": [
          {
            "title": "Greg Norman Polo Umbrella Coral Guava",
            "vendor": "Greg Norman",
            "tags": ["G2S22K469", "Ladies", "Polo"]
          }
          // omitted for brevity
        ]
      }
    }
  }
}

As you can see, the first product returned, doesn't actually match the tag that I'm filtering by. Any idea if I'm doing something wrong here?

I saw that they added it too but it seems work on the newer version 2023-04 but my problem is how to query more than one tag? I tried to use AND or to separate them with commas and that didn't work.

Did you ever get a response to this? I'm looking to filter tags with the OR method.

I found a solution:

TLDR: you need to install the "Search and Discovery" app, and enable searching by tags from there.
