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"
"medianate age" » "medianaate age", "mediaate age", "mediasate age"
"medianatete age" » "medianaatete age", "mediaatete age", "mediasatete age", "medianamente 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 ("medianate age"))) OR ((("mediante age") OR ("medianatete age"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"median age\") OR (\"medianate age\"))) OR (((\"mediante age\") OR (\"medianatete age\"))))*".
• Removing quotes may allow a broader search: (((( median age ) OR ( medianate age ))) OR ((( mediante age ) OR ( medianatete age ))))*.
