• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((tay lang) OR (tay quang)) xa hoi. hieu ((va cao) or (va dao)) tuc va trinh hoa cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((tay lang) OR (tay quang)) xa hoi. hieu ((va cao) OR (va dao)) tuc va trinh hoa cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((tay lang) OR (tay quang)) xa hoi. hieu ((va cao) or (va dao)) tuc va trinh hoa cua viet*".
