• If you are trying to use Boolean operators, they must be ALL CAPS: (((("online brand research documents") OR ((("online board research documents") OR ("online toward research documents"))))) OR ("online brand search document")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"online brand research documents\") or (((\"online board research documents\") OR (\"online toward research documents\"))))) or (\"online brand search document\"))".
• Removing quotes may allow a broader search: (((( online brand research documents ) or ((( online board research documents ) OR ( online toward research documents ))))) or ( online brand search document )).
• Adding a wildcard symbol may retrieve word variants: (((("online brand research documents") or ((("online board research documents") OR ("online toward research documents"))))) or ("online brand search document"))*.
