No, it's just what I said. Read the original Jira (from Solr 1.4!):
https://issues.apache.org/jira/browse/SOLR-1321

You, the user, need to specify and  populate a reversed wildcard field if
that is want you want - it is not magic and not automatic.

This should be documented as an "expert" feature. And there should be doc
on how to use it.

I do have some doc in my e-book, with some examples, but even that does not
show the complete end-to-end config and schema.
