• If you are trying to use Boolean operators, they must be ALL CAPS: te san ky tang van hoi. hieu ((va tham) OR (van tham)) soc va hanh vi ((cuu tre) OR (cua cu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te san ky tang van hoi. hieu ((va tham) OR (van tham)) soc va hanh vi ((cuu tre) or (cua cu))".
