• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y ((sang ma) OR (tang ma)) hoi. lieu va thanh loai va dinh ((vi cua) OR (doi cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y ((sang ma) OR (tang ma)) hoi. lieu va thanh loai va dinh ((vi cua) or (doi cua)) tre".
