• If you are trying to use Boolean operators, they must be ALL CAPS: thu xach ((tay lang) OR (tai lang)) xa hoi. hieu ((thi cham) OR (thi hai)) xuc van hanh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu xach ((tay lang) OR (tai lang)) xa hoi. hieu ((thi cham) or (thi hai)) xuc van hanh vi cua tre".
