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