• Removing quotes may allow a broader search: (((( program _ codigo. ) OR ( programaadas drawn codigo. ))) OR ( programaaaasaaar plc codigo. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("program _ codigo.") OR ("programaadas drawn codigo."))) OR ("programaaaasaaar plc codigo."))*.
