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