• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((dang tao) OR (sang tao)) khoi. lieu ha nam tuc xa ((van tai) OR (tvan tai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((dang tao) OR (sang tao)) khoi. lieu ha nam tuc xa ((van tai) or (tvan tai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((dang tao) OR (sang tao)) khoi. lieu ha nam tuc xa ((van tai) or (tvan tai)) cua tre*.
