• Performing a fuzzy search may retrieve terms with similar spellings: so ((sac ky) OR (cac ky)) dong hoa hoi. hieu tu cam xuc ban thanh va ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sac ky) OR (cac ky)) dong hoa hoi. hieu tu cam xuc ban thanh va ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sac ky) OR (cac ky)) dong hoa hoi. hieu tu cam xuc ban thanh va ((cua tre) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: so ((sac ky) OR (cac ky)) dong hoa hoi. hieu tu cam xuc ban thanh va ((cua tre) or (cua triet))*.
