A Couple of Search Tips… Search for web pages within specific domains:

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 SearchExample: “capital punishment” site:.edu

Filetype SearchExample: “capital punishment” filetype:pdf

Use advanced search instead of search commands for the same result

Combine the two commandsExample:“capital punishment” site:.edu filetype:pdf
