• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu xanh - hanh trong van ((((nhung phong) OR (nguong phong))) or (nung phong)) nam tang van~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh trong van ((((nhung phong) OR (nguong phong))) OR (nung phong)) nam tang van*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh trong van ((((nhung phong) OR (nguong phong))) or (nung phong)) nam tang van*".
