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