• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach v nang ma hoi. hieu ((va thanh) OR (gia thanh)) duc va hanh ((vai cua) OR (than cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach v nang ma hoi. hieu ((va thanh) OR (gia thanh)) duc va hanh ((vai cua) or (than cua)) tre".
• Adding a wildcard symbol may retrieve word variants: tu sach v nang ma hoi. hieu ((va thanh) OR (gia thanh)) duc va hanh ((vai cua) or (than cua)) tre*.
