• Performing a fuzzy search may retrieve terms with similar spellings: so sach ty mang xa hoi. lieu va nay luc ((va dan) or (va dau)) ((va chua) OR (ca chua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty mang xa hoi. lieu va nay luc ((va dan) OR (va dau)) ((va chua) OR (ca chua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty mang xa hoi. lieu va nay luc ((va dan) or (va dau)) ((va chua) OR (ca chua)) te*".
