• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. ((hieu va) OR (lieu va)) dau luc ban ((hang moi) OR (hang doi)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. ((hieu va) or (lieu va)) dau luc ban ((hang moi) OR (hang doi)) cua tre".
