• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty tang van hoa. hieu ve cam ((luc va) OR (tuc va)) hanh ((di cuu) OR (di cau)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty tang van hoa. hieu ve cam ((luc va) or (tuc va)) hanh ((di cuu) OR (di cau)) tre".
