• Performing a fuzzy search may retrieve terms with similar spellings: hoc nhiet nang - ((hanh mang) OR (hanh trang)) cua dong ((duong tinh) or (duong sinh)) toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc nhiet nang - ((hanh mang) OR (hanh trang)) cua dong ((duong tinh) OR (duong sinh)) toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc nhiet nang - ((hanh mang) OR (hanh trang)) cua dong ((duong tinh) or (duong sinh)) toan cau*".
