Perhaps you should try some spelling variations:
"median age" » "mediana age", "media age", "mediante age"
"mediantea age" » "medianatea age", "mediatea age", "mediantetea age", "mediante age", "mediana age"
"medianate age" » "medianaate age", "mediaate age", "medianteate age", "mediante age", "mediana age"
"mediantete age" » "medianatete age", "mediatete age", "mediantetete age", "mediante 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 ("mediantea age"))) OR ((("medianate age") OR ("mediantete age"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"median age\") OR (\"mediantea age\"))) OR (((\"medianate age\") OR (\"mediantete age\"))))".
• Removing quotes may allow a broader search: (((( median age ) OR ( mediantea age ))) OR ((( medianate age ) OR ( mediantete age )))).
• Adding a wildcard symbol may retrieve word variants: (((("median age") OR ("mediantea age"))) OR ((("medianate age") OR ("mediantete age"))))*.
