• If you are trying to use Boolean operators, they must be ALL CAPS: ((( (nurse OR nurkse) OR (purse OR pursue)) practitioner ) OR ( course practitioner ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((( (nurse OR nurkse) OR (purse OR pursue)) practitioner ) OR ( course practitioner ))~".
• Adding a wildcard symbol may retrieve word variants: ((( (nurse OR nurkse) OR (purse OR pursue)) practitioner ) OR ( course practitioner ))*.
