Looking for help with Solr on Drupal.org infrastructure

Last night we enabled Pivots recommendations on Drupal.org. We've been working on Pivots for almost 18 months and I think it represents an exciting new type of Drupal.org service. Today pivots uses a custom indexer written in Java. That indexer reads the content on Drupal.org and then indexes it to the masterdb-other.drupal.org a database server outside our main Drupal.org database servers.

See: http://mrzhou.cms.si.umich.edu/diagram-pivots-recommendation-system-do

What if instead of having a custom indexer designed just for Pivots we had a rich indexer with lots of meta information and semantic tagging. See http://buytaert.net/drupal-the-semantic-web-and-search

The goal here is not to replace Drupal core search, or to replace Xaphian, they each serve their purpose. The goal is to move the Drupal.org infrastructure to provide more service oriented architectures so that innovators and entrepreneurs can mash up content on Drupal.org. If you have time, and the skills we can work together to propose a plan and do some prototypes. I think there are lots of exciting services that would be possible with a first class search service like Solr on Drupal.org. See http://drupal.org/project/apachesolr for more details.

Cheers,
