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