Perhaps you should try some spelling variations:
"median age" » "mediana age", "media age", "medias age"
"medianateate age" » "medianaateate age", "mediaateate age", "mediasateate age", "medianamente age"
"mediantetea age" » "medianatetea age", "mediatetea age", "mediastetea age"
"medianaatetetea age" » "medianaaatetetea age", "mediaaatetetea age", "mediasaatetetea 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 ("medianateate age"))) OR ((("mediantetea age") OR ("medianaatetetea age"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"median age\") OR (\"medianateate age\"))) OR (((\"mediantetea age\") OR (\"medianaatetetea age\"))))*".
• Removing quotes may allow a broader search: (((( median age ) OR ( medianateate age ))) OR ((( mediantetea age ) OR ( medianaatetetea age ))))*.
