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