• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu tinh)) - canh sinh vat ((dang cong) OR (bang cong)) van thanh tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu tinh)) - canh sinh vat ((dang cong) or (bang cong)) van thanh tu".
