te dung » tieu dung, tien dung, tin dung
cac cau » cac mau, bac cau, ca cau
ca chu » cua chu, ca chua, cac chu
ban ke » ban kem, ban ve, ban le
ke y » ke ky, ke o
tuyen » truyen, quyen

• If you are trying to use Boolean operators, they must be ALL CAPS: tuyen tap ((((((cac cau) OR (ca chu))) OR (cac khu))) OR (cach thuc)) đe co ban ke y te dung cong.
• Adding a wildcard symbol may retrieve word variants: tuyen tap ((((((cac cau) or (ca chu))) or (cac khu))) or (cach thuc)) đe co ban ke y te dung cong*.
