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