• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("online rand research documents") OR ("online rand research arguments"))) OR ((("online hand research contents") OR ("online hand research content"))))) 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 rand research arguments\"))) or (((\"online hand research contents\") OR (\"online hand research content\"))))) or (\"online ((rand search) or (random search)) document\"))".
• Removing quotes may allow a broader search: (((((( online rand research documents ) or ( online rand research arguments ))) or ((( online hand research contents ) OR ( online hand research content ))))) or ( online ((rand search) or (random search)) document )).
• Adding a wildcard symbol may retrieve word variants: (((((("online rand research documents") or ("online rand research arguments"))) or ((("online hand research contents") OR ("online hand research content"))))) or ("online ((rand search) or (random search)) document"))*.
