• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((((((((3 john) OR (13 john))) OR (((20 john) OR (2008 john))))) OR (24 john))) OR (((((21 john) OR (((22 john) OR (12 john))))) OR (25 john))))) OR (4 john)) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((((3 john) or (13 john))) or (((20 john) OR (2008 john))))) or (24 john))) or (((((21 john) or (((22 john) or (12 john))))) or (25 john))))) or (4 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((((3 john) or (13 john))) or (((20 john) OR (2008 john))))) or (24 john))) or (((((21 john) or (((22 john) or (12 john))))) or (25 john))))) or (4 john)) %27 estate%22*.
