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