No, it doesn't (though you can get a port of GNU's grep here). You could try to use Windows's Find applet, but my experience of it is that it is seriously broken.
You could of course write a script that scans through a directory, reading files and searching for || yourself of course. In fact, you could rewrite grep() in PHP if you wanted.
