• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ty) OR (sach y)) ((nang ma) OR (sang ma)) hoi. thi cong cac tuc cua dao vinh cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ty) or (sach y)) ((nang ma) OR (sang ma)) hoi. thi cong cac tuc cua dao vinh cuu tre~".
• Adding a wildcard symbol may retrieve word variants: su ((sach ty) or (sach y)) ((nang ma) OR (sang ma)) hoi. thi cong cac tuc cua dao vinh cuu tre*.
