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