I do not know vi well but I do not see how it could be simpler than ctr-alt-s
in emacs.  There, while you are filling the regular expression you can see the
text that the incomplete regular expression is matching. If you put one letter
more and the matching you had does not match anymore, it goes to next
ocurrence of that regular expression you have in the text.
