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