Hi LS, I think you should consult regex syntax first. There are many possibilities to do so. One of them is (\w)* means greedy match of as many words as possible. There are some regex tutorials on the internet, google for them. Boost.Regex is a lib which supports the syntax of different regex specifications (Perl, POSIX ...)

Which mean, if I'm looking for 'main' I don't want to match 'mainVariation' but things like 'main(int' or 'one,main,two'. The equivalent of what you will find in any decent search tool :). I look through regex documentation and didn't find anything about that. If it's not implemented, is it planned to be ? Or shall the Boost.Regex user handle this applying some pre-processing on the regular expression to perform such task ? Thank you.
