• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. ((hieu vu) OR (hieu va)) cham soc van anh ve ((cuu tre) OR (cu tren))~.
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. ((hieu vu) or (hieu va)) cham soc van anh ve ((cuu tre) or (cu tren))*.
