It depends whether it's a Perl regex or a POSIX regex.  Perl matching rules 
are documented here: 
http://www.boost.org/libs/regex/doc/syntax_perl.html#what and the 
Leftmost-Longest rule used by POSIX regexes is documented here: 
http://www.boost.org/libs/regex/doc/syntax_leftmost_longest.html

Does this give you the information you require?
