• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (co sach)) huy hoang van hoi. hieu ((ve coc) OR (ve cac)) tuc va trinh quan cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (co sach)) huy hoang van hoi. hieu ((ve coc) OR (ve cac)) tuc va trinh quan cuu tre*".
