Perhaps you should try some spelling variations:
"median age" » "mediana age", "media age", "mediante age"
"medianteate age" » "medianateate age", "mediateate age", "medianteteate age"
"medianteteate age" » "medianateteate age", "mediateteate age", "medianteteteate age", "medianteate age"
"mediantete age" » "medianatete age", "mediatete age", "mediantetete age", "mediante 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 (\"medianteteate age\"))))) OR (\"mediantete age\"))~".
• Removing quotes may allow a broader search: (((( median age ) OR ((( medianteate age ) OR ( medianteteate age ))))) OR ( mediantete age ))~.
• Adding a wildcard symbol may retrieve word variants: (((("median age") OR ((("medianteate age") OR ("medianteteate age"))))) OR ("mediantete age"))*.
