I'm not able to use the filters properly. Here's my situation:

I'm using <http://internal.company.com:8000/nameA/nameB/date> as my base URL.

I want to retrieve specific file names below this URL.

There are  ~200  folders, and ~200 sub folders. So approx 40,000 total folders
below the base URL.

Each subfolder (lowest point in tree) has a bunch of files (.html, .xml,
.txt).  I only want 
to copy files named messages.gz or messages.log.gz.

How do I copy only message.gz and messages.log.gz?
