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