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