I use some simple regular expression in 'windows search', 'notepad++ search', 'ultraedit search', 'visual studio ENV'. The regular expression is so precisely that I cannot remember all of them. So each time when I using RE in a programming language(c/cpp) or a tool, I will try and try again, until the result is I want. Before I post this topic, I only try '*', '.', '+', '?' for RE matching. After I post the topic, I learned the '{n,m}', '-'. Thanks a lot. By the way, find a help doc is another way.
