The actual type passed to DirectoryProviderHelper is actually going to
limit the scope of properties being read, so the property key is not
just the "indexBase" constant but it is as documented:

   "hibernate.search.default.indexBase"

or with the index name:

   "hibernate.search.Animals.indexBase"

just search for "indexBase" in the reference documentation, there are
many examples of how to use this property.

I guess it might surprise you - it's indeed not pointed out in the
Hibernate Search documentation - that *all* configuration properties
can be set via System properties as well, as with all the Hibernate
core properties.

You should have shared it! So you've been using Hibernate Search for
more than a year, you should have let us know about the annoying
things earlier to stretch them out ;-)

Fair enough, I guess it was initially expected that someone out there
would have prepared the directories correctly, but I agree let's
change that to INFO. Could you open a JIRA, and maybe you could patch
the code and send a pull request?

Thanks for your feedback!
