• 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 ((cao cua) OR (ca cua)) tre~.
• 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 ((cao cua) OR (ca cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ky trong xay hoi. ((hieu va) or (lieu va)) cam duc van dinh ((cao cua) OR (ca cua)) tre*.
