The Solr Project refers to drupal.org as being an example of the search that is possible.

Looking at Drupal.org module list (http://drupal.org/node/27367) Solr is not listed.

So how is the drupal.org site searching set up? Is there a page somewhere explaining how drupal.org search is setup?

I have been searching and failed to find it. Thought I am certain it does exist.
