• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach v) OR (sach va)) lang ha hoi. hieu ((va cam) OR (va cac)) xuc ban thanh doi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach v) OR (sach va)) lang ha hoi. hieu ((va cam) or (va cac)) xuc ban thanh doi cua te".
