• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"programa lddel codigo.\") OR (\"programa de codigo.\"))) OR (\"programacion ddel codigo.\"))~".
• Removing quotes may allow a broader search: (((( programa lddel codigo. ) OR ( programa de codigo. ))) OR ( programacion ddel codigo. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("programa lddel codigo.") OR ("programa de codigo."))) OR ("programacion ddel codigo."))*.
