Drupal Solr Next Gen - the refactoring

Like most folk, I've heard of Drupal. But I'd not heard of Solr. I read it as "soir" and, not surprisingly, searching wasn't finding anything.

Anyway, for those, like me, who haven't heard of Solr, here's a brief description and a couple of related links:

Solr is the popular, blazing fast open source enterprise search platform from the Apache Lucene project. Its major features include powerful full-text search, hit highlighting, faceted search, dynamic clustering, database integration, and rich document (e.g., Word, PDF) handling. Solr is highly scalable, providing distributed search and index replication, and it powers the search and navigation features of many of the world's largest internet sites.
