• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (lieu tinh)) - canh tranh chap truong cong tan ((toan ban) OR (van ban))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (lieu tinh)) - canh tranh chap truong cong tan ((toan ban) OR (van ban))*.
