• Performing a fuzzy search may retrieve terms with similar spellings: thuat khanh ly vang x hoi. hieu ve cau truc va hanh vai ((((cua tre) OR (dua tren))) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat khanh ly vang x hoi. hieu ve cau truc va hanh vai ((((cua tre) OR (dua tren))) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat khanh ly vang x hoi. hieu ve cau truc va hanh vai ((((cua tre) OR (dua tren))) or (cuu tre))*".
