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