• If you are trying to use Boolean operators, they must be ALL CAPS: te sach _ lang xa hoi. ((lieu va) OR (((thien van) OR (thi van)))) lam dua ban thanh tai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach _ lang xa hoi. ((lieu va) or (((thien van) OR (thi van)))) lam dua ban thanh tai cua tre*".
