How can I find out if my property names are being indexed?

When I run <swish-e -T INDEX_METANAMES> from the command line, I am only
seeing the swish meta names (swishdoctitle, etc).

I have this line in my config file and all of my html docs have those four
meta tags:
PropertyNames Subject Description Keywords Author

I want to  return these items in my results.

Thanks for any help.
