• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"te sach doanh tri\") OR (\"te cac doanh tri\"))) OR (\"te sach danh tri\"))".
• Removing quotes may allow a broader search: (((( te sach doanh tri ) OR ( te cac doanh tri ))) OR ( te sach danh tri )).
• Adding a wildcard symbol may retrieve word variants: (((("te sach doanh tri") OR ("te cac doanh tri"))) OR ("te sach danh tri"))*.
