• If you are trying to use Boolean operators, they must be ALL CAPS: (("nguyen can minh chi") OR ((("nguyen nhu minh khai") OR ("nguyen nhu minh pham")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"nguyen can minh chi\") or (((\"nguyen nhu minh khai\") OR (\"nguyen nhu minh pham\"))))".
