Pyspark - Data Quality Management with Pydeequ

Question

I'm trying create Analysis with PatterMatch Analyzer

PatternMatch docs\

But each attempt ends with a 0.0% result evet if I pass r'.*' as regex.

Im trying to catch all strings with 3 _ sign and 2 digits XYZ_00

                    .addAnalyzer(PatternMatch(
                        column = 'MY_COL',
                        pattern_regex = r'^\S{3}.\d{2}',
                        where = None
                ))

Has anyone managed to do it ? In docs i found out something that suggest it is not completed.
