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