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