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