Google Search Tips

Sometimes what you need is buried several pages into millions of search results. Add these limits to your searches to get more manageable and relevant results:

  • " " to search words as a phrase instead of individually - "international development"
  • site: to limit to a particular website or domain - site:gov or site:un.org
  • filetype: to limit to a filetype - filetype:pdf or filetype:xls

Typing "international development" site:un.org filetype:pdf will limit your results to publications in pdf form (i.e. reports and working papers) hosted on the United Nations website that refer to the phrase international development. You can also use Google's Advanced Search form.
