• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((((((20 john) OR (21 john))) OR (((2((3 john) OR (4 john))) OR (1((3 john) OR (4 john))))))) OR (((((((22 john) OR (12 john))) OR (1 john))) OR (((25 john) OR (5 john))))))) OR (((3 john) OR (4 john)))) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((20 john) or (21 john))) or (((2((3 john) OR (4 john))) or (1((3 john) OR (4 john))))))) or (((((((22 john) or (12 john))) or (1 john))) or (((25 john) or (5 john))))))) or (((3 john) OR (4 john)))) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((20 john) or (21 john))) or (((2((3 john) OR (4 john))) or (1((3 john) OR (4 john))))))) or (((((((22 john) or (12 john))) or (1 john))) or (((25 john) or (5 john))))))) or (((3 john) OR (4 john)))) %27 estate%22*.
