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