• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuat san) OR (thuat lanh)) ly hang xa hoi. hieu vien bach duc va hanh vi ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuat san) or (thuat lanh)) ly hang xa hoi. hieu vien bach duc va hanh vi ((cua te) OR (cua tu))".
• Adding a wildcard symbol may retrieve word variants: ((thuat san) or (thuat lanh)) ly hang xa hoi. hieu vien bach duc va hanh vi ((cua te) OR (cua tu))*.
