Databases use three primary operators to determine how you want your search to be run:
Use "" for phrase searches
Additionally, the use of () will allow the database to know how you want your search terms to be interpreted:
("first year experience" OR FYE) AND (activities OR assignments) AND engagement
will bring much more relevant results than if you ran the search like:
"first year experience" OR FYE AND activities OR assignments AND engagement
as the use of the parentheses let the database know which terms should be used as synonyms, and which terms needed to be present as a separate concept.
