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