[PATCH 43/54] Fix test syntax errors and update filter tests for coverage - Remove corrupted duplicate code in get_filtered_or test - Fix get_filtered_match test to use correct pattern syntax - Fix get_filtered_search test to use correct pattern syntax The match() and search() functions expect quoted string patterns, not /pattern/ regex syntax.
