• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky nang cau hoa. hieu ve ((chat huu) OR (pham huu)) ((va thanh) or (ban hanh)) vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang cau hoa. hieu ve ((chat huu) OR (pham huu)) ((va thanh) OR (ban hanh)) vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang cau hoa. hieu ve ((chat huu) OR (pham huu)) ((va thanh) or (ban hanh)) vai cua tre*".
