Regular expression \w doesn't appear to work
Attempting to perform an REGEXP_EXTRACT() using \w as a parameter in the query, however, it does not appear to be allowed as a parameter at the moment even though the example provided uses the parameter.
"REGEXP_EXTRACT(birth date, 'foo(\w+)bar')"
Even attempting to use "REGEXP_EXTRACT(field, '\w')" returns "Could not parse formula".
Is this a known bug or has the feature not been implemented yet?
