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