• Performing a fuzzy search may retrieve terms with similar spellings: ((tu cac) or (((thuat lanh) OR (thuat lap)))) ky lang van hoi. hieu va am thuc va dan vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cac) OR (((thuat lanh) OR (thuat lap)))) ky lang van hoi. hieu va am thuc va dan vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cac) or (((thuat lanh) OR (thuat lap)))) ky lang van hoi. hieu va am thuc va dan vi cuu tre".
