• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chau tinh) OR (cua tinh)) - nhanh tang luan ((nhung cong) OR (dung cong)) dan toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chau tinh) or (cua tinh)) - nhanh tang luan ((nhung cong) OR (dung cong)) dan toan tap*".
