• Performing a fuzzy search may retrieve terms with similar spellings: su sach ly lang xa hoi. hieu van ((lam truc) OR (nam truc)) va danh vi ((cuu tre) or (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ly lang xa hoi. hieu van ((lam truc) OR (nam truc)) va danh vi ((cuu tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ly lang xa hoi. hieu van ((lam truc) OR (nam truc)) va danh vi ((cuu tre) or (cau treo))*".
