• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((tang ma) OR (tang van)) hoi. thi nang cam tuc va hanh ((vai cua) OR (hai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((tang ma) or (tang van)) hoi. thi nang cam tuc va hanh ((vai cua) OR (hai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((tang ma) or (tang van)) hoi. thi nang cam tuc va hanh ((vai cua) OR (hai cua)) tre*.
