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