• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu xanh)) - hanh trung cap dung ((cong dan) OR (cong san)) toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (chieu xanh)) - hanh trung cap dung ((cong dan) or (cong san)) toan ban".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) OR (chieu xanh)) - hanh trung cap dung ((cong dan) or (cong san)) toan ban*.
