Search Techniques
Truncation in a database search allows you to use a symbol (usually an asterisk *) to find all words that begin with the same root, helping you capture variations of a term—for example, educat retrieves education, educator, and educational.
Boolean operators are words like AND, OR, and NOT that help refine database searches. For example, in psychology research:
-
anxiety AND depression finds studies discussing both topics,
-
anxiety OR stress finds studies on either concept, and
-
anxiety NOT children excludes studies focused on children.
Using quotation marks around a phrase in a database search creates an exact search, meaning the database will only return results where the words appear together in that exact order—for example, searching "cognitive behavioral therapy" ensures you find sources with that full phrase, not just the individual words scattered throughout the text.
