• If you are trying to use Boolean operators, they must be ALL CAPS: toc hieu manh - hanh trong ((quan doan) OR (chuan doan)) phuong dan ((toan cau) OR (toan cao)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc hieu manh - hanh trong ((quan doan) OR (chuan doan)) phuong dan ((toan cau) or (toan cao))".
