Anonymus user can´t see node wich are not set to 'Send to all affiliates'

Hi guys,
so.. I have 3 sites over domains module and the search results always returns me contents from all domains. So, I took some nodes and disable the option "Send to all affiliates'" hoping that would be visible only on their own domains.
But they´re not visible anymore. If do a Login, the content is there, but if i do a logout, I can´t see them and they are not show in the search anymore.
Any idea?
thanks
