Think about it: search engines crawl thousands, maybe even millions and billions, of pages or records trying to match your search term with results. You're going to be absolutely overwhelmed with results if you only enter a single search term. You're also going to find a lot of completely irrelevant stuff.
So how can you improve your chances?
Come up with multiple search terms and combine them using the options described here.
Combining search terms with AND will:
Search for politics = 296 million results
Search for "college student" AND politics = 43 million results more focused on your topic
Search for "college student" AND politics AND "2008 election" = 543,000 more relevant results
Search for Adam Smith = 38,700,000 results
Search for "Adam Smith" = 2,730,000 results
Search for theory of relativity = 3,430,000 results
Search for "theory of relativity" = 856,000 results
Follow this activity and keep notes on your group's powerpoint slides.
STEP 1: Brainstorm with your group and determine two possible subtopics that you can use for this activity.
STEP 2: Identify keywords that you would like to use to find information sources for each subtopic.
STEP 3: Use the same keywords and run the same search in the two databases listed below. Repeat for your second subtopic.
STEP 4: Summarize your searches on your group's slides, using the template provided.
STEP 5: Prepare yourselves to present your searches to the rest of the class. Your entire group's presentation should take no more than 2 minutes.
