• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ky ((nang ma) OR (sang ma)) hoa. hieu ve ((cham xuc) or (chat xuc)) va hanh va cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky ((nang ma) OR (sang ma)) hoa. hieu ve ((cham xuc) OR (chat xuc)) va hanh va cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky ((nang ma) OR (sang ma)) hoa. hieu ve ((cham xuc) or (chat xuc)) va hanh va cua tre*".
