• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sac ky) OR (sai ky)) hang va hoi. hieu ve cham xuc ((toan hanh) OR (tang hanh)) tai cua tre".
• Adding a wildcard symbol may retrieve word variants: su ((sac ky) OR (sai ky)) hang va hoi. hieu ve cham xuc ((toan hanh) OR (tang hanh)) tai cua tre*.
