• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu lang) OR (hieu lang)) - hanh ban ((cua dang) OR (cua ban)) cong dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu lang) or (hieu lang)) - hanh ban ((cua dang) OR (cua ban)) cong dan than cau".
