• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((ha dong) OR (kha nang)) - hanh trang qua dung cong dan ((toan cau) OR (toan cao)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((ha dong) or (kha nang)) - hanh trang qua dung cong dan ((toan cau) OR (toan cao))".
