Use the search command site:.edu or site:.gov to limit
your search to educational or government web sites.

Search for specific document file types:
Use the command filetype:pdf or filetype:doc to limit
your search to Adobe PDF or Word files.
Domain Search
Example: “capital punishment” site:.edu
Filetype Search
Example: “capital punishment” filetype:pdf
Use advanced search instead of search
commands for the same result
Combine the two commands
Example:
“capital punishment” site:.edu filetype:pdf
