• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - ((thanh luan) OR (trinh luan)) van dung cong ((van tam) OR (van tai)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - ((thanh luan) or (trinh luan)) van dung cong ((van tam) OR (van tai)) cao".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - ((thanh luan) or (trinh luan)) van dung cong ((van tam) OR (van tai)) cao*.
