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