Thus I was wondering: which is the actual algorithm used by regex_search? Does it take into consideration other things beside the biggest length?
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?
I'm using perl regular expressions (the default) I'll take a those links, thanks!
