• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ky) OR (sac ky)) dang ha noi. hieu ve cam tuc va thanh vi ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) dang ha noi. hieu ve cam tuc va thanh vi ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sac ky)) dang ha noi. hieu ve cam tuc va thanh vi ((cua tre) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sac ky)) dang ha noi. hieu ve cam tuc va thanh vi ((cua tre) or (cua triet))*.
