Perhaps you should try some spelling variations:
"mediante age" » "mediante el", "mediante la", "mediante un", "medianate age", "mediate age", "mediaste age"
"median age" » "mediana age", "media age", "medias age"
"medianteteteate age" » "medianateteteate age", "mediateteteate age", "mediasteteteate age"
"medianateteteate age" » "medianaateteteate age", "mediaateteteate age", "mediasateteteate age"

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

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