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