• If you are trying to use Boolean operators, they must be ALL CAPS: ho chiet tach - ((hanh tinh) OR (thanh tinh)) va ((nhung trong) OR (nhung tuong)) cac toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - ((hanh tinh) or (thanh tinh)) va ((nhung trong) OR (nhung tuong)) cac toan ban*".
