• If you are trying to use Boolean operators, they must be ALL CAPS: (((("aboriginal australianss") OR ("aboriginal australians"))) OR ((("original australian") OR ("aboriginal australia")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"aboriginal australianss\") or (\"aboriginal australians\"))) or (((\"original australian\") OR (\"aboriginal australia\"))))".
• Removing quotes may allow a broader search: (((( aboriginal australianss ) or ( aboriginal australians ))) or ((( original australian ) OR ( aboriginal australia )))).
• Adding a wildcard symbol may retrieve word variants: (((("aboriginal australianss") or ("aboriginal australians"))) or ((("original australian") OR ("aboriginal australia"))))*.
