• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu tinh) OR (lieu tinh)) - hanh trong cuong dung hong van ((tuan cau) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu tinh) OR (lieu tinh)) - hanh trong cuong dung hong van ((tuan cau) or (toan cao))*".
