isearch and yank word doubt

[Luca Ferrari]

Hi all,
according to the manual the C-s C-w yanks the next word the cursor is
on as the string to search with isearch. Often I found myself having
the cursor in the middle of a word, so I have to go back to the
beginning and then do the yank, is there a better way to instrument
C-s C-w to get the word the cursor is in?

Thanks,
Luca
