• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach v) OR (sach va)) nang x hoi. hieu qua ((tham soc) OR (tham nuoc)) va danh dieu cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach v) or (sach va)) nang x hoi. hieu qua ((tham soc) OR (tham nuoc)) va danh dieu cua tre*".
