Perhaps you should try some spelling variations:
"mediante age" » "mediante el", "mediante la", "mediante un", "medianate age", "mediate age", "mediaste age"
"median age" » "mediana age", "media age", "medias age"
"medianateate age" » "medianaateate age", "mediaateate age", "mediasateate age", "medianamente age"
"medianateteteteate age" » "medianaateteteteate age", "mediaateteteteate age", "mediasateteteteate 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 ((("mediante age") OR ((("medianateate age") OR ("medianateteteteate age"))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"median age\") OR (((\"mediante age\") OR (((\"medianateate age\") OR (\"medianateteteteate age\"))))))*".
• Removing quotes may allow a broader search: (( median age ) OR ((( mediante age ) OR ((( medianateate age ) OR ( medianateteteteate age ))))))*.
