"Do not search this page" option in page content?

[KO]

I would like to see such an option in admin department when editing content. If Something is hidden with FrontEndUsers and with CustomContent there should be an easy way for editor to say that "this should not be publicly searchable".  What this "tick could do is put in page content. I thinks this is same for normal Search module and for piSearch module.

Or is there such an option allready that I'm not aware?
