• Performing a fuzzy search may retrieve terms with similar spellings: (((("program _ codigo.") OR ("programasaas el codigo."))) OR ("programaaacion visual codigo."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"program _ codigo.\") OR (\"programasaas el codigo.\"))) OR (\"programaaacion visual codigo.\"))".
• Removing quotes may allow a broader search: (((( program _ codigo. ) OR ( programasaas el codigo. ))) OR ( programaaacion visual codigo. )).
• Adding a wildcard symbol may retrieve word variants: (((("program _ codigo.") OR ("programasaas el codigo."))) OR ("programaaacion visual codigo."))*.
