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