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