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