• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach kem) OR (sac ky)) nang xa hoi. lieu va ((cham xuc) OR (chat xuc)) va hanh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach kem) or (sac ky)) nang xa hoi. lieu va ((cham xuc) OR (chat xuc)) va hanh vi cua tre".
