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