• Performing a fuzzy search may retrieve terms with similar spellings: doi chieu tinh - hanh trung cua ((nhung phuong) or (dung phuong)) ((doan toan) OR (dan toan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu tinh - hanh trung cua ((nhung phuong) OR (dung phuong)) ((doan toan) OR (dan toan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu tinh - hanh trung cua ((nhung phuong) or (dung phuong)) ((doan toan) OR (dan toan)) cau*".
