Bear Hunt provides a quick and powerful Solr Search API bundle that sets up a Solr Server and a default node index. It also automatically configures a faceted Views search pane right out of the box and places the view and facets at /search within a panel. Upon installation, Drupal's core search will be disabled.
You will need to download the Solr PHP client library from here. This library can be placed at sites/all/libraries and must be present before enabling the Bear Hunt module.
