• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach y) OR (sac ky)) ((nang xa) OR (lang xa)) hoi. hieu ve cao duc va danh doi cuu tre".
• Adding a wildcard symbol may retrieve word variants: thu ((sach y) OR (sac ky)) ((nang xa) OR (lang xa)) hoi. hieu ve cao duc va danh doi cuu tre*.
