1. In the original search, add site:.edu (or .gov ; .org ; .net) at the end of the search terms.
Example: music careers site:.edu
2. If you use Google’s Advanced Search, one option is to narrow the search by site or domain.
.com = commercial site
.net =network provider
.edu =education - school or university
.mil = military website
.gov = government website
.com, .net, and .org sites are less regulated, meaning anyone can register for a website with that domain. .edu, .mil, and .gov sites are MORE REGULATED, and tend to be more reliable.
