how can I isearch in selected region?

how can I isearch in selected region?

[luciferleo]

given a region selected by C-@, you can kill-region by C-w, you can
kill-ring-save by M-w

given a buffer, you can isearch-forward by C-s, you can
isearch-backward by C-r

but how can you combine them? I cannot find a isearch-forward-region or
something related.

You can narrow the buffer to the region with ``C-x n n'', perform
any operation that would affect the entire buffer only on the
narrowed region and widen the view of the current buffer to the
full buffer contents with ``C-x n w'' again.

I regularly use this to replace-string or replace-regexp in a
region and it works quite fine :)

I use replace-string without narrowing, with transient-mark-mode, and
it works good too.
