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