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