• If you are trying to use Boolean operators, they must be ALL CAPS: so sach thu tang van hoe. hieu va cham soc va hanh vi ((((cua tu) OR (cua tuc))) OR (cua cu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach thu tang van hoe. hieu va cham soc va hanh vi ((((cua tu) OR (cua tuc))) or (cua cu))".
• Adding a wildcard symbol may retrieve word variants: so sach thu tang van hoe. hieu va cham soc va hanh vi ((((cua tu) OR (cua tuc))) or (cua cu))*.
