Use search engines when you want to find information on a narrow subject, or to get a specific page. After putting in your key words, a search engine will look for them, and return a list of sites containing your search criteria (your search terms).

The results are not selected or reviewed for you. You will need to review the results for credibility and reliability.

Some common commands used in search engines include the use of quotes " " for words adjacent (phrase searching), the plus sign + to include terms and the minus sign - to eliminate terms. Most search engines can search using simple Boolean: AND/OR/NOT.
