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