• If you are trying to use Boolean operators, they must be ALL CAPS: te sach 2 ((nang xa) OR (sang ma)) hoi. hieu so cham doc va ((danh kien) OR (dinh kien)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach 2 ((nang xa) or (sang ma)) hoi. hieu so cham doc va ((danh kien) OR (dinh kien)) cua te*".
