Perhaps you should try some spelling variations:
"median age" » "mediana age", "media age", "mediante age"
"medianate age" » "medianaate age", "mediaate age", "medianteate age", "mediante age", "mediana age"
"medianatete age" » "medianaatete age", "mediaatete age", "medianteatete age", "mediantete age", "medianate age"
"medianteatete age" » "medianateatete age", "mediateatete age", "medianteteatete 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 ((("medianatete age") OR ("medianteatete age"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"median age\") OR (\"medianate age\"))) OR (((\"medianatete age\") OR (\"medianteatete age\"))))*".
• Removing quotes may allow a broader search: (((( median age ) OR ( medianate age ))) OR ((( medianatete age ) OR ( medianteatete age ))))*.
