• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach ky) OR (sach ty)) nang xa hoi. lieu va cham luoc ((van hanh) OR (van anh)) lai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach ky) OR (sach ty)) nang xa hoi. lieu va cham luoc ((van hanh) or (van anh)) lai cua triet".
• Adding a wildcard symbol may retrieve word variants: vu ((sach ky) OR (sach ty)) nang xa hoi. lieu va cham luoc ((van hanh) or (van anh)) lai cua triet*.
