• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sac ky) OR (cac ky)) dang xa hoi. hieu ve cam thu van dung cho ((cua tre) OR (cua te)).
• Adding a wildcard symbol may retrieve word variants: so ((sac ky) or (cac ky)) dang xa hoi. hieu ve cam thu van dung cho ((cua tre) or (cua te))*.
