When you search library databases, you will use keywords related to your research topic. Then use the keywords to combine them using Boolean Operators into search strings (or phrase searching) to improve your search. Boolean Operators are simple words (AND, OR, and NOT) that are used to connect and define the relationship between keywords.
Remember that the database can't interpret what you mean, so you have to be clear and specific with your searches in order to control the results.
Truncation is a technique that broadens your search to include various word endings and spellings.
