How to search using the quick find box on top right?

I am searching for SB 123. Quick Find returns other SBs but not the one I want. Does the revision make a difference?

Frequently Asked Questions: 

To limit the results in Quick find it initially does an Exact Match search and display all issues that exactly match the input.

If it finds no results it asks if you want to do a wild card search.

In your example it never shows gets to the wild card option because there are exact matches.

You will need to force the wild card search by adding a % and all variants/revisions will show.
