• If you are trying to use Boolean operators, they must be ALL CAPS: (("functions based using tools") OR ((("deim based using tools") OR ("deim based nursing tools")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"functions based using tools\") or (((\"deim based using tools\") OR (\"deim based nursing tools\"))))".
