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