Advanced Searching: Use Boolean
Using Boolean logic means using command to connect your search words. It helps you find better information and avoud the irrelevant. The Boolean connectors are And, Or, and Not.
Example: What is the impact of college binge drinking on grades?
Identify the keywords in your question. For this example College, binge drinking, and grades.
And, connects these concepts so you get results that have both search terms. You are telling the search engine to look for items that contain all of your search terms. This will narrow your search so you will retrieve fewer results.
For example, College AND "Binge drinking" AND Grades will give you articles represented in the shaded area. With
Or connects these concepts so you get results that have at least one (or more) of your search terms. You are telling the search engine to look for any of these search terms. Use it with synonyms to broaden your search. You will retrieve a greater number of results.
For example College OR University will give you results that contain either term represented in all the shaded areas.
Combine these search strategies for an even more powerful search. Use parentheses to separate groups of search words.
For example, you may want to combine the following keywords into one search: College, University, "Binge drinking", alcohol, grades, "academic achievement"
(College OR University) AND ("Binge drinking" OR alcohol) AND (grades OR "academic achievement")
Not will eliminate terms from a search. If you want to search for articles about alcohol but not other drugs, you could search for (College OR University) AND ("Binge drinking" OR alcohol) AND (grades OR "academic achievement") NOT drugs
