Compiled regular expression objects support the following methods and attributes:
The optional second parameter pos gives an index in the string where the search is to start; it defaults to 0. The '' pattern character will match at the index where the search is to start.
The optional parameter endpos limits how far the string will be searched; it will be as if the string is endpos characters long, so only the characters from pos to endpos will be searched for a match.
The optional pos and endpos parameters have the same meaning as for the match() method.
