• If you are trying to use Boolean operators, they must be ALL CAPS: (((("online hand search document") OR ((("online sand research documents") OR ("online sand research students"))))) OR ((("online hand research arguments") OR ("online band research arguments")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"online hand search document\") or (((\"online sand research documents\") OR (\"online sand research students\"))))) or (((\"online hand research arguments\") or (\"online band research arguments\"))))".
• Removing quotes may allow a broader search: (((( online hand search document ) or ((( online sand research documents ) OR ( online sand research students ))))) or ((( online hand research arguments ) or ( online band research arguments )))).
• Adding a wildcard symbol may retrieve word variants: (((("online hand search document") or ((("online sand research documents") OR ("online sand research students"))))) or ((("online hand research arguments") or ("online band research arguments"))))*.
