I'm looking for a way to query one of the big boy Search Engines or a tool that also accesses pretty much the entire web and I want it to return unique domains instead of unique pages. For example, right now if I search Google for 'copyright jelsoft' it will give me millions of forum pages. But I want to know how many forums there are running on Jelsoft's software so I'm looking to filter it by unique domains. Is there any such query or tool?
I don't think that would be possible UNLESS you have a database with the web in it. :\ Because there are more factors than just going through the sites and filtering them out. You would have to have the capability of going through every site within the results (which would be millions), get just the domain names and then compare for duplicates. Then of course there would be those sites that do not have the VBulletin text at the bottom, or other small factors that you may run into... It would be extemely difficult to do something like this. But would be cool if you could.
I wasn't very clear in describing my needs. I'm not so much interested in a full list actually, the total count is enough. Bit like DISTINCT in SQL.
