Perhaps you should try some spelling variations:
"median age" » "mediana age", "media age", "medias age"
"medianteate age" » "medianateate age", "mediateate age", "mediasteate age", "medianamente age"
"medianteateate age" » "medianateateate age", "mediateateate age", "mediasteateate age", "medianamenteate age"
"mediaaate age" » "mediante age", "mediate 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 (\"medianteateate age\"))) OR (\"mediaaate age\"))))~".
• Removing quotes may allow a broader search: (( median age ) OR ((((( medianteate age ) OR ( medianteateate age ))) OR ( mediaaate age ))))~.
• Adding a wildcard symbol may retrieve word variants: (("median age") OR ((((("medianteate age") OR ("medianteateate age"))) OR ("mediaaate age"))))*.
