• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach y)) nang ma hoa. hieu ve ((cham luc) OR (nhan luc)) va thanh ly cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sach y)) nang ma hoa. hieu ve ((cham luc) or (nhan luc)) va thanh ly cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sach y)) nang ma hoa. hieu ve ((cham luc) or (nhan luc)) va thanh ly cua tre*.
