• If you are trying to use Boolean operators, they must be ALL CAPS: thu sai ky ((tang ha) OR (tang ma)) noi. hieu vu cham xuc ((ban thanh) OR (ban hanh)) ve cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sai ky ((tang ha) or (tang ma)) noi. hieu vu cham xuc ((ban thanh) OR (ban hanh)) ve cua tre".
• Adding a wildcard symbol may retrieve word variants: thu sai ky ((tang ha) or (tang ma)) noi. hieu vu cham xuc ((ban thanh) OR (ban hanh)) ve cua tre*.
