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