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