Boolean searching task

In order to get more hits related to my keywords from university sources I first tried the following search in Google: “amstrad cpc 464″ +university. I put the words “amstrad cpc 464″ in quotation marks so I would get an match for those exact words and not each word individually. I added “+ university” to also search for the word university, however the results I got were not just from universities. After some trial and error I got the required results by using Google to search for: “amstrad cpc 464″ +site:*.edu, the result was only three sites all from Universities.

I did the same search in Copernic and although I got more results the same three sites that appeared in the Google search still seemed to be the best match.
