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