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