• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu xanh - canh ((((tranh chua) OR (trinh chuan))) or (tranh chap)) dung cong tan thanh ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - canh ((((tranh chua) OR (trinh chuan))) OR (tranh chap)) dung cong tan thanh ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - canh ((((tranh chua) OR (trinh chuan))) or (tranh chap)) dung cong tan thanh ban*".
