Perhaps you should try some spelling variations:
"Argentine peso" » "Argentine pero", "Argentine paso", "Argentine pesos"
"Argentine pesto" » "Argentine puesto", "Argentine peston", "Argentine presto", "Argentine pestos", "Argentine peste", "Argentine pesta"
"Argentine eso" » "Argentine esos"
"Argentine esto" » "Argentine estos", "Argentine este", "Argentine esta"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("Argentine peso") OR ("Argentine pesto"))) OR ((("Argentine eso") OR ("Argentine esto"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"Argentine peso\") OR (\"Argentine pesto\"))) OR (((\"Argentine eso\") OR (\"Argentine esto\"))))".
• Removing quotes may allow a broader search: (((( Argentine peso ) OR ( Argentine pesto ))) OR ((( Argentine eso ) OR ( Argentine esto )))).
• Adding a wildcard symbol may retrieve word variants: (((("Argentine peso") OR ("Argentine pesto"))) OR ((("Argentine eso") OR ("Argentine esto"))))*.
