• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ((ky lang) OR (ky nang)) ha noi. hieu van cham ((soc van) OR (sac van)) thanh vai cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ((ky lang) OR (ky nang)) ha noi. hieu van cham ((soc van) or (sac van)) thanh vai cua tu".
• Adding a wildcard symbol may retrieve word variants: su sac ((ky lang) OR (ky nang)) ha noi. hieu van cham ((soc van) or (sac van)) thanh vai cua tu*.
