• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu nganh) OR (chieu tinh)) - hoang dung ((tai nhung) OR (tai hung)) cong dan toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu nganh) or (chieu tinh)) - hoang dung ((tai nhung) OR (tai hung)) cong dan toan ban".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu nganh) or (chieu tinh)) - hoang dung ((tai nhung) OR (tai hung)) cong dan toan ban*.
