• If you are trying to use Boolean operators, they must be ALL CAPS: te ((xach tay) OR (sach tu)) nang ma hoi. hieu qua cam ((xuc van) OR (duc van)) hanh vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((xach tay) or (sach tu)) nang ma hoi. hieu qua cam ((xuc van) OR (duc van)) hanh vi cua tre*".
