• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (hoc sach)) y lang xa hoi. ((hieu va) OR (lieu va)) cam dua ban thanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) or (hoc sach)) y lang xa hoi. ((hieu va) OR (lieu va)) cam dua ban thanh vai cua tre*".
