Perhaps you should try some spelling variations:
"median age" » "mediana age", "media age", "medias age"
"medianaate age" » "medianaaate age", "mediaaate age", "mediasaate age"
"mediantetea age" » "medianatetea age", "mediatetea age", "mediastetea age"
"medianateatetetea age" » "medianaateatetetea age", "mediaateatetetea age", "mediasateatetetea 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 ("medianaate age"))) OR ((("mediantetea age") OR ("medianateatetetea age"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"median age\") OR (\"medianaate age\"))) OR (((\"mediantetea age\") OR (\"medianateatetetea age\"))))*".
• Removing quotes may allow a broader search: (((( median age ) OR ( medianaate age ))) OR ((( mediantetea age ) OR ( medianateatetetea age ))))*.
