• Removing quotes may allow a broader search: (((( literatura arabes e isela. ) or ( literatura es de isaac. ))) or ( literatura de de islam. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("literatura arabes e isela.") or ("literatura es de isaac."))) or ("literatura de de islam."))*.
