• If you are trying to use Boolean operators, they must be ALL CAPS: (( e learning resource agencies. ) OR ( wbi ((teaching resource) OR (teacher resource)) curse. ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( e learning resource agencies. ) or ( wbi ((teaching resource) OR (teacher resource)) curse. ))~".
• Adding a wildcard symbol may retrieve word variants: (( e learning resource agencies. ) or ( wbi ((teaching resource) OR (teacher resource)) curse. ))*.
