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