By default, matches are performed on substrings. For example, program matches GL_PROGRAM. To anchor your expressions, use the standard regular expression boundary matchers such as ^ for the beginning of a line, and $ for the end of a line. For example, program$ matches GL_CURRENT_PROGRAM but not GL_PROGRAM_PIPELINE_BINDING.

If the filter you type is not a valid regular expression, the Filter or Search box goes red and the error is shown as a tooltip.
