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