• The words AND, OR and NOT may confuse the search; try adding quotes: "su dang y nang xa hoi. hieu van cam ((loc va) OR (tuc xa)) hanh vi ((cua te) OR (cua tre))".
• Adding a wildcard symbol may retrieve word variants: su dang y nang xa hoi. hieu van cam ((loc va) OR (tuc xa)) hanh vi ((cua te) OR (cua tre))*.
