• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ((ky lang) OR (ky nang)) xa hoi. lieu va cam ((cuc ban) OR (cuu ban)) hang dieu cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ((ky lang) OR (ky nang)) xa hoi. lieu va cam ((cuc ban) or (cuu ban)) hang dieu cua tre".
• Adding a wildcard symbol may retrieve word variants: su sac ((ky lang) OR (ky nang)) xa hoi. lieu va cam ((cuc ban) or (cuu ban)) hang dieu cua tre*.
