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