• Performing a fuzzy search may retrieve terms with similar spellings: so sach ty ((hang xa) OR (hoang xa)) hoi. hieu ve cap nuoc ((va danh) or (va dinh)) di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty ((hang xa) OR (hoang xa)) hoi. hieu ve cap nuoc ((va danh) OR (va dinh)) di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty ((hang xa) OR (hoang xa)) hoi. hieu ve cap nuoc ((va danh) or (va dinh)) di cua te*".
