• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ty hang van hoi. hieu van cac tuc va nang oi ((su triet) OR (ve triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ty hang van hoi. hieu van cac tuc va nang oi ((su triet) or (ve triet))".
