While developing on new project which was created not by you, the software always is good for searching something..
Big plus of the software is that it is searching in sub directories... and it searches in text files! And most important it works just great!
Searches text files for strings and combination of strings. Has useful or / and / and not search combinations, and can also use regular expressions. New in version 3, is the built-in viewer / editor that highlights the matched strings and lines.
