• The words AND, OR and NOT may confuse the search; try adding quotes: "((archivo historico) or (((archivs history) or (((archival history) or (((archiving history) OR (searching history)))))))) de ((la defensa) or (la defense)) nacional (mexico)".
• Adding a wildcard symbol may retrieve word variants: ((archivo historico) or (((archivs history) or (((archival history) or (((archiving history) OR (searching history)))))))) de ((la defensa) or (la defense)) nacional (mexico)*.
