[development] Re: [iai-members] Federated search tools

I got this mail from a list. Could Drupal do this with some search engine? Louis is a world leader in Information Architecture and a Publisher. Best Gunnar Louis Rosenfeld wrote:

I'm looking for a search tool that will do this:

1) Search multiple domains that would be predetermined by me (a la Rollyo) 2) Return results via RSS 3) Is free (or cheap)

I thought that Google might somehow support this via its API. It might, but I can't figure out how to make Google search multiple domains.

Any ideas?
