There is a nice pattern you can follow to search for yanked text. Then you don't even have to type the word in itself, if you've navigated to it by means other than a search.
In summary, if you're on the first character of the word you want to search for:
v
e
y
/
Ctrl-r
0
Enter
(then continue to next match with n or N)
However *
(or #
) accomplishes pretty much the same thing as all these commands. The only difference is you can be flexible by how much of the word you specify (rather than e, to the end of the word, you can select as much as you want to, e.g. 9l)
