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