Boolean Operators

Boolean operators connect search terms and can narrow or expand your search.

AND narrows search results, contains all the search terms
pizza AND soda = all results will have both terms pizza and soda, though not necessarily next to each other

OR expands search results, contains at least 1 of the search terms
soda OR pop = results would have the soda or pop

NOT excludes term after NOT
soda NOT pop = results would have soda but not the term pop


Creating Search Terms

Since you cannot simply type a question or sentence into a search box, you need to consider what term(s) you need to use to get the results you are looking for. Remember to take into account synonyms. For instance, if you are looking for information on weight lifting, you might also try weight training. To get keywords, consider doing some background reading on your research question to see what terms are commonly used for the topic you are investigating.
