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