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