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