• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach ty)) nang cao hoi. lieu va cam xuc van dinh viet ((su triet) OR (su viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sach ty)) nang cao hoi. lieu va cam xuc van dinh viet ((su triet) or (su viet))".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sach ty)) nang cao hoi. lieu va cam xuc van dinh viet ((su triet) or (su viet))*.
