Parallel indexing for Apache Solr Search IntegrationOct 24, 2012

Recently I've been involved in drupal.org by upgrading the site to the latest version of Apache Solr Search Integration (from 6.x-1.x to 6.x-3.x, and in the near future to 7.x-1.x). This upgrade path is necessary as we still want to have a unified search capability across Drupal 6 and Drupal 7 sites, for example groups.drupal.org and drupal.org.
