• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu tinh - hanh ((tran van) or (luan van)) duong huong ((manh toan) OR (tinh toan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - hanh ((tran van) OR (luan van)) duong huong ((manh toan) OR (tinh toan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - hanh ((tran van) or (luan van)) duong huong ((manh toan) OR (tinh toan)) cau".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - hanh ((tran van) or (luan van)) duong huong ((manh toan) OR (tinh toan)) cau*.
