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