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