• Performing a fuzzy search may retrieve terms with similar spellings: thu canh ky nang ma hoa. hieu van tham luc va ((danh vi) OR (danh di)) ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu canh ky nang ma hoa. hieu van tham luc va ((danh vi) OR (danh di)) ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu canh ky nang ma hoa. hieu van tham luc va ((danh vi) OR (danh di)) ((cua tre) or (cua triet))".
