If you are in the manual, then `i x RET'.

If `x' is not in the index then you will need to search
for it: `C-s x C-s C-s...' or likewise, with `C-M-s', if
`x' is a regexp.

If `x' is indexed multiple times then you can continue to
visit indexed occurrences in the manual, by using `,' -
just as the message tells you.  E.g.:

 "Found `defun' in Index.  (11 total; use `,' for next)"

You can also use `I', which creates a virtual Info node
with the results of an index search.

If you don't know which manual to check, try `M-x info-apropos'.

All of this is well explained in the (small) Info manual,
in particular, (info) `Search Index'.

I suggest you start with the Info manual, before trying to use
any other manual.  Your time spent there will be rewarded.

There is a reason that the Info manual is presented first in
the list of manuals (by default).  Its description:

 "How to use the documentation browsing system."

It will answer that how-to question far better than answers
you'll get here, I'm guessing (including this answer).
