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