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