Advanced Find and Replace Description:

Advanced Find and Replace is exactly what the name implies. It's fast,
easy to use, and a great time-saver for programmers and Webmasters in
particular. This powerful utility lets you perform text searches on your
local computer as if you were using an Internet search engine. It features
support for operators that allow you to specify phrases, words to insist on
(+), and words to ignore (-). You can easily apply filespec, date, and size
filters to speed up the search. The program also allows you to replace
simple or multiline strings. Specify your search-and-replace strings, then
choose the action you'd like to take: delete the search string, insert text
before or after it, or simply replace it. You can even apply multiple
changes to large groups of files in a single operation and use optional
confirmation if you need to be more selective. Excellent documentation is
included.
