• If you are trying to use Boolean operators, they must be ALL CAPS: (tuyen OR truyen) tap ((cac khoan) OR (((cach thuc) OR (anh thuc)))) đe co ban ve ky te dung trong~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(tuyen or truyen) tap ((cac khoan) or (((cach thuc) OR (anh thuc)))) đe co ban ve ky te dung trong~".
• Adding a wildcard symbol may retrieve word variants: (tuyen or truyen) tap ((cac khoan) or (((cach thuc) OR (anh thuc)))) đe co ban ve ky te dung trong*.
