• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sac ky)) nang x hoi. lieu va nam ((duoc ban) OR (buoc ban)) hanh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sac ky)) nang x hoi. lieu va nam ((duoc ban) OR (buoc ban)) hanh vai cua te".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) or (sac ky)) nang x hoi. lieu va nam ((duoc ban) OR (buoc ban)) hanh vai cua te*.
