• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((((((((2((c john) OR (1 john))) OR (((23 john) OR (3 john))))) OR (((c john) OR (1 john))))) OR (24 john))) OR (((((21 john) OR (22 john))) OR (((25 john) OR (5 john))))))) OR (4 john)) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((((2((c john) or (1 john))) or (((23 john) OR (3 john))))) or (((c john) or (1 john))))) or (24 john))) or (((((21 john) or (22 john))) or (((25 john) or (5 john))))))) or (4 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((((2((c john) or (1 john))) or (((23 john) OR (3 john))))) or (((c john) or (1 john))))) or (24 john))) or (((((21 john) or (22 john))) or (((25 john) or (5 john))))))) or (4 john)) %27 estate%22*.
