• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu sang) OR (chiet tach)) - hanh trang va ((nhung cong) OR (dung cong)) san toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sang) or (chiet tach)) - hanh trang va ((nhung cong) OR (dung cong)) san toan ban*".
