• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty ((xang xa) or (((mang xa) OR (lang xa)))) hoi. hieu va cam xuc va tinh ha cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((xang xa) OR (((mang xa) OR (lang xa)))) hoi. hieu va cam xuc va tinh ha cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((xang xa) or (((mang xa) OR (lang xa)))) hoi. hieu va cam xuc va tinh ha cua viet".
