Can I use internal tags to create collections?

HI,

I was wondering if I could use internal tags to create collections of posts. I am in the process of setting up a collection of newsletters. I have made the internal tags and added the following to the routes.yaml file.

..........

  /The Crack/:
    permalink: /newsletter/{slug}/
    template: index
    filer: tag:hash-ck+hash-2022

..........

However, I am not sure what to do from there. I have made a test post, and although I can view the post when I click on it to open it directly, I can not view my post in the collection when I go to mjwolfe.me/newsletter, despite tagging the post with the internal tags #ck and #2022``.

I am not sure what I have done wrong.

Am I not able to use internal tags to create collections?

Thanks

Mel
