• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh ky nang x hoi. hieu cua cac ((tac ban) OR (tai ban)) thanh tiep ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh ky nang x hoi. hieu cua cac ((tac ban) OR (tai ban)) thanh tiep ((cua tre) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: so sanh ky nang x hoi. hieu cua cac ((tac ban) OR (tai ban)) thanh tiep ((cua tre) or (cua triet))*.
