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