apt-file list shows only two files for nginx package

I wanted to check how many files come with the nginx package. However the corresponding command seems to indicate that the package comes with only two files (?) $ apt-file list nginx nginx: /usr/share/doc/nginx/changelog.Debian.gz nginx: /usr/share/doc/nginx/copyright How is this possible given that e.g. the corresponding list for apache2 contains 197 files?
