- The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"khoa hoc ((van tham) OR (van thanh)) pha\\") or (\\"hoa hoc ((van tham) OR (van thanh)) pha\\"))\"".
- Removing quotes may allow a broader search: (( khoa hoc ((van tham) OR (van thanh)) pha ) or ( hoa hoc ((van tham) OR (van thanh)) pha )).
