• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sac) or (tu cac)) ky lang xa hoi. thi hanh lam quoc ((ban thanh) OR (ban hang)) di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu cac)) ky lang xa hoi. thi hanh lam quoc ((ban thanh) OR (ban hang)) di cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) or (tu cac)) ky lang xa hoi. thi hanh lam quoc ((ban thanh) OR (ban hang)) di cua tre*".
