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