Being able to search for the issue number and find it
Problem to solve
I cannot search for the issue number in the search box:

Whereas the issue exists: https://gitlab.com/gitlab-org/gitlab-ee/issues/12937
Intended users
All users searching for issue numbers
Further details
The idea is that you don't have to manually type in the issue number in the URL to get to it, you can search for it in the project box.
Proposal
Consider the issue numbers as searchable items, and present it in the search results. I would propose either the raw issue number 12345 or a #12345 would be acceptable.
Permissions and Security
No permission needed, as long as the issue is public and in a project that the user can see.
