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