Hey there @aksjm2, what happens when you click on the hastags that have a dash in them? Does it try searching but is unable to find any results? Or does the search just not happen at all?
I tested this with version 5.15 of Mattermost, and version 4.2.1 of the client, and I got this result when I clicked on #qa-xxx :
Hi @aksjm2, I did some more testing with a similar version of Mattermost as the one you are using (5.13.1), and indeed I could not search for any hashtags that had a dash in them. On the other hand, regular hashtags worked just fine.
On the other hand, my previous test that I included in my screenshot was from 5.15.1. I believe that this may have been a bug, but it has been fixed in the latest version.
Your organization may need to upgrade Mattermost to fix this issue.
