Perhaps you should try some spelling variations:
"median age" » "mediana age", "media age", "mediante age"
"medianteate age" » "medianateate age", "mediateate age", "medianteteate age"
"mediantete age" » "medianatete age", "mediatete age", "mediantetete age", "mediante age"
"medianteatete age" » "medianateatete age", "mediateatete age", "medianteteatete age"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"median age\") OR (\"medianteate age\"))) OR (((\"mediantete age\") OR (\"medianteatete age\"))))~".
• Removing quotes may allow a broader search: (((( median age ) OR ( medianteate age ))) OR ((( mediantete age ) OR ( medianteatete age ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("median age") OR ("medianteate age"))) OR ((("mediantete age") OR ("medianteatete age"))))*.
