• If you are trying to use Boolean operators, they must be ALL CAPS: te ((cac ky) OR (sai ky)) nang xa hoi. hieu ((van cau) OR (ke cau)) duc va tinh vi cua tre.
• Adding a wildcard symbol may retrieve word variants: te ((cac ky) or (sai ky)) nang xa hoi. hieu ((van cau) or (ke cau)) duc va tinh vi cua tre*.
