• Performing a fuzzy search may retrieve terms with similar spellings: (((("ngoc anh truong") OR ("ngoc anh trong"))) or ((("ngo thang truong") or ("ngo hong thuong"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ngoc anh truong") OR ("ngoc anh trong"))) OR ((("ngo thang truong") OR ("ngo hong thuong"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ngoc anh truong\") OR (\"ngoc anh trong\"))) or (((\"ngo thang truong\") or (\"ngo hong thuong\"))))*".
• Removing quotes may allow a broader search: (((( ngoc anh truong ) OR ( ngoc anh trong ))) or ((( ngo thang truong ) or ( ngo hong thuong ))))*.
