• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"van hoa thong ky can vuong.\\") OR (\\"van hoa thong ky ((dang vuong) OR (dang truong)).\\"))\"".
• Removing quotes may allow a broader search: (( van hoa thong ky can vuong. ) OR ( van hoa thong ky ((dang vuong) OR (dang truong)). )).
