• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu xanh - hanh trang va ((((nhung cong) OR (nhung don))) or (hang cong)) tap doan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh trang va ((((nhung cong) OR (nhung don))) OR (hang cong)) tap doan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh trang va ((((nhung cong) OR (nhung don))) or (hang cong)) tap doan cau*".
