• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thu sang ma hoi. hieu ((qua ca) OR (qua cai)) su ((va thanh) or (va tinh)) lap cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu sang ma hoi. hieu ((qua ca) OR (qua cai)) su ((va thanh) OR (va tinh)) lap cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu sang ma hoi. hieu ((qua ca) OR (qua cai)) su ((va thanh) or (va tinh)) lap cua te*".
