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