yea but unfortunately it's not that good ... think it's better than default search but a still too slow as a mean for code navigation (atleast for my taste). it's mainly due to needing to hit enter, which escapes everything, there should be a way to hit next occurrence and prev without leaving the /search box.
In combination with this it's almost as effective. Personally I'd use ctags and the http://vimdoc.sourceforge.net/htmldoc/tagsrch.html#tag-comma... search functionality of the tags. But I'll give you that normal text searching in emacs is a tiny bit more efficient :)
