• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((nang o) OR (nang co)) hoi. lieu va ((tham duoc) OR (tham nuoc)) va thanh van cua cu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((nang o) OR (nang co)) hoi. lieu va ((tham duoc) or (tham nuoc)) va thanh van cua cu".
