• If you are trying to use Boolean operators, they must be ALL CAPS: ((archivo historico) OR (archivs history)) de la ((defense nacional) OR (defensa nacional)) (mexico).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((archivo historico) or (archivs history)) de la ((defense nacional) OR (defensa nacional)) (mexico)".
• Adding a wildcard symbol may retrieve word variants: ((archivo historico) or (archivs history)) de la ((defense nacional) OR (defensa nacional)) (mexico)*.
