• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (cach tu)) nang xa hoi. hieu va cham luoc van hanh diem ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (cach tu)) nang xa hoi. hieu va cham luoc van hanh diem ((cua te) OR (cua tu))".
