• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) OR (sac ky)) ((tang xa) or (tang ma)) hoi. hieu va nam xuc va tinh di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sac ky)) ((tang xa) OR (tang ma)) hoi. hieu va nam xuc va tinh di cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sac ky)) ((tang xa) or (tang ma)) hoi. hieu va nam xuc va tinh di cua triet".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sac ky)) ((tang xa) or (tang ma)) hoi. hieu va nam xuc va tinh di cua triet*.
