• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((((((3 john) OR (20 john))) OR (((24 john) OR (94 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 (20 john))) or (((24 john) OR (94 john))))) or (((((21 john) or (((22 john) or (12 john))))) or (25 john))))) or (4 john)) %27 estate%22".
