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