If you look at http://taskotron-dev.fedoraproject.org/resultsdb/testcases you can see that we now have namespaced testcases, so e.g. upgradepath is now qa.upgradepath. We also have some new test cases, like scratch.libabigail. But the search box in top right corner of resultsdb frontend only shows these hardcoded options:
{F50411}
When I select "upgradepath", it only searches for upgradepath, but not for qa.upgradepath test case. I can't type in my own string, so I can't search for qa.upgradepath manually, nor I can search for scratch.libabigail.

I believe we need to get rid of the hardcoded list, and either provide a popup that will show all existing testcases in the database and allow users to filter them dynamically and pick the one they want, or we just need to provide a plain text field and require the users to know what they are looking for. Implementing wildcard matching would be very helpful (so that I can do *upgradepath).
