qa: search qa tests failing in CI

Created by: davejrt

search tests are failing in the regression pipline in CI. These tests need to be updated or removed if they're no longer valid.

The errors with the exception of one are due to strings not matching, which on face value just appears that the expected string needs to be changed because the tests are old/no longer valid.

The other error is a timeout.
