• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach v) OR (sach ha)) nang ma hoi. hieu vu cham o va danh kien ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach v) or (sach ha)) nang ma hoi. hieu vu cham o va danh kien ((cua tre) OR (cua te))".
