Test Case Search Page does include Test Plan as a filtering option

[YouWhy]

Is your feature request related to a problem? Please describe.
When I go to the Test Case Search page, I cannot search for Test Cases that belong to a Test Plan. Also, in the results displayed, I dont see what Test Plans a Test Case is associated with.

Describe the solution you'd like
Consider allowing user to choose Test Plan on the Test Case Search Page. Consider displaying what test plans the test cases are associated with in the output of the results.

Describe alternatives you've considered
Cant think of any

Additional context
I would use Test Plans as a way to group test cases together. So, I should have the ability to search for Test Cases within a test plan.

Yes I have a similar use case. I am trying to find out all the unassigned test cases and the only way I can see is to navigate into each test case.
