• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (nhiet nang)) - sach dung luan hung cong dan ((than cao) OR (thai cao)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (nhiet nang)) - sach dung luan hung cong dan ((than cao) OR (thai cao))".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (nhiet nang)) - sach dung luan hung cong dan ((than cao) OR (thai cao))*.
