• Performing a fuzzy search may retrieve terms with similar spellings: thu cach tu nang ma hoi. hieu ((va cham) or (ve chat)) duc va thanh dai ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu cach tu nang ma hoi. hieu ((va cham) OR (ve chat)) duc va thanh dai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu cach tu nang ma hoi. hieu ((va cham) or (ve chat)) duc va thanh dai ((cua tre) OR (cua triet))".
