• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky trong xay hoi. ((hieu va) OR (lieu va)) cam duc van dinh dao ((cuu tre) OR (cau treo))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky trong xay hoi. ((hieu va) or (lieu va)) cam duc van dinh dao ((cuu tre) OR (cau treo))~".
• Adding a wildcard symbol may retrieve word variants: tu sach ky trong xay hoi. ((hieu va) or (lieu va)) cam duc van dinh dao ((cuu tre) OR (cau treo))*.
