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