• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sac ky) OR (sai ky)) lang ha noi. thien ((van cham) OR (van chat)) duc ban hanh lai cua thuoc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sac ky) OR (sai ky)) lang ha noi. thien ((van cham) or (van chat)) duc ban hanh lai cua thuoc".
• Adding a wildcard symbol may retrieve word variants: su ((sac ky) OR (sai ky)) lang ha noi. thien ((van cham) or (van chat)) duc ban hanh lai cua thuoc*.
