Just to make sure you know: contacting support might be a
better/faster option if you are using nginx-plus.

Quoting http://nginx.org/r/proxy_cache_purge:
: If the cache key of a purge request ends with an asterisk (“*”), all cache
: entries matching the wildcard key will be removed from the cache.
Note "ends with" - only wildcards at the end of the cache key are
supported. This doesn't mean "at the end of the URL" though, as
cache keys can be arbitrary configured (see
http://nginx.org/r/proxy_cache_key).

If you want to purge resources like this on a regular basis,
re-structuring your proxy_cache_key might be an option. For
example, you may split "document/{id}/report" into "document/{id}"
and "/report", and put "/report" into the cache key first.
