• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((lang van) OR (dang van)) hoe. hieu van nam ((xuc va) OR (luc va)) thanh va cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((lang van) or (dang van)) hoe. hieu van nam ((xuc va) OR (luc va)) thanh va cua tre".
