Boolean Operators: Using the AND Operator
The search Religion AND tattoos is represented. Using this example, articles that included both the word religion and the word tattoo would be returned. Articles with only one of those words somewhere in the text would be ignored. As more keywords are added to a search, the number of articles will decrease. When too many keywords are used, the database will often return no results. For this reason, starting with a couple keywords first is a good way to gauge how many articles are available before getting more specific.
The diagram below is a visual representation of the search used above.The lighter colored sections represent all the articles available in the Academic Search Complete database that contain either the word religion or the word tattoo. The darkened intersection is articles that contain both of these keywords within the article. The AND operator is most useful for finding information on topics with two or more components.
