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