• Performing a fuzzy search may retrieve terms with similar spellings: hoc chieu xanh - hanh mang cua ((truong con) OR (truong ton)) ((dan toan) or (manh toan)) ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - hanh mang cua ((truong con) OR (truong ton)) ((dan toan) OR (manh toan)) ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - hanh mang cua ((truong con) OR (truong ton)) ((dan toan) or (manh toan)) ban*".
