• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach y ((nang ma) OR (sang ma)) hoi. hieu ve cac luc quan anh ((di cua) OR (vai cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach y ((nang ma) OR (sang ma)) hoi. hieu ve cac luc quan anh ((di cua) or (vai cua)) tre*".
