Perhaps you should try some spelling variations:
"median age" » "mediana age", "media age", "mediante age"
"medianaatea age" » "medianaaatea age", "mediaaatea age", "medianteaatea age"
"medianate age" » "medianaate age", "mediaate age", "medianteate age", "mediante age", "mediana age"
"medianatetetea age" » "medianaatetetea age", "mediaatetetea age", "medianteatetetea age", "mediantetetea age", "medianatetea 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 ((((("medianaatea age") OR ("medianate age"))) OR ("medianatetetea age"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"median age\") OR (((((\"medianaatea age\") OR (\"medianate age\"))) OR (\"medianatetetea age\"))))".
• Removing quotes may allow a broader search: (( median age ) OR ((((( medianaatea age ) OR ( medianate age ))) OR ( medianatetetea age )))).
• Adding a wildcard symbol may retrieve word variants: (("median age") OR ((((("medianaatea age") OR ("medianate age"))) OR ("medianatetetea age"))))*.
