Perhaps you should try some spelling variations:
archivo historico » archivio storico, archiving historical
archivs history » archives history, archival history, archiving history
archive history » archives history, archival history, archiving history
la defensa » la defense, la depense
a defense » a defence, _ defense

You may be able to get more results by adjusting your search query.

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