• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty nang xa hoi. thi nang cham duc va danh vi ((((cuu tre) OR (cau tren))) or (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang xa hoi. thi nang cham duc va danh vi ((((cuu tre) OR (cau tren))) OR (cua tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang xa hoi. thi nang cham duc va danh vi ((((cuu tre) OR (cau tren))) or (cua tre))".
• Adding a wildcard symbol may retrieve word variants: te sach ty nang xa hoi. thi nang cham duc va danh vi ((((cuu tre) OR (cau tren))) or (cua tre))*.
