The case that blocks us now is related to bug numbers mentioned in messages.
It is common to search for a conversations on the particular bug through history.
Say you posted a link "https://mattermost.atlassian.net/browse/PLT-1961".
And than mentioned bug PLT-1961 or even just by the number 1961.
You now have three messages you want to see in the search results:
* https://mattermost.atlassian.net/browse/PLT-1961
* PLT-1961
* 1961
Now to the reality:
* "*PLT*" -> PLT-1961
* "*1961*" -> 1961
* "1961" -> 1961
* "PLT-1961" -> --
* "*PLT-1961*" -> --
Sad & unacceptable
