• Performing a fuzzy search may retrieve terms with similar spellings: toc ((sach ky) OR (sac ky)) lang xa hoi. lieu va cao suc va hang tai ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach ky) OR (sac ky)) lang xa hoi. lieu va cao suc va hang tai ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ky) OR (sac ky)) lang xa hoi. lieu va cao suc va hang tai ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: toc ((sach ky) OR (sac ky)) lang xa hoi. lieu va cao suc va hang tai ((cua tre) or (cua te))*.
