• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"online rand research documents\") or (((((\"online hand research contents\") OR (\"online hand research content\"))) or (\"online land research contents\"))))) or (\"online ((rand search) or (random search)) document\"))".
• Removing quotes may allow a broader search: (((( online rand research documents ) or ((((( online hand research contents ) OR ( online hand research content ))) or ( online land research contents ))))) or ( online ((rand search) or (random search)) document )).
• Adding a wildcard symbol may retrieve word variants: (((("online rand research documents") or ((((("online hand research contents") OR ("online hand research content"))) or ("online land research contents"))))) or ("online ((rand search) or (random search)) document"))*.
