• If you are trying to use Boolean operators, they must be ALL CAPS: te sach 2 ((nang ma) OR (sang ma)) hoi. hieu ve cham tuc va vanh dai ((su triet) OR (ve triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach 2 ((nang ma) OR (sang ma)) hoi. hieu ve cham tuc va vanh dai ((su triet) or (ve triet))".
