• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sac ky) OR (sai ky)) nang ma hoi. hieu van chat truc ((va danh) OR (va dan)) dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sac ky) OR (sai ky)) nang ma hoi. hieu van chat truc ((va danh) or (va dan)) dai cua tre".
• Adding a wildcard symbol may retrieve word variants: thu ((sac ky) OR (sai ky)) nang ma hoi. hieu van chat truc ((va danh) or (va dan)) dai cua tre*.
