Apache Solr Search Integration

Revolutionize your Drupal search experience

This module integrates Drupal with the Apache Solr search platform. Solr search can be used as a replacement for core content search and boasts both extra features and better performance. If you're looking for Apache Solr integration, this is possibly the best option available.

Drupal 7

Drupal 7 version of the module is almost ready to go to a RC status.
Faceted search is supported if you use the facet API module. Facets will be available for you ranging from content author to taxonomy to arbitrary fields.
This version also includes :

• Search Pages (Multiple search pages with optionally customized search results)
• Multiple Environment (support for Multiple Solr Servers)
• Range Query type, that in combination with facet API and Facet Api Slider a very rich faceting experience delivers to the end user.
• Supports Custom Entity indexing through hooks. Examples such as Apachesolr Commerce,
  Apachesolr User indexing and
  Apachesolr Term can give you a headstart in developing your own indexing code for your entity.

Careful : If you want to use other contributed modules you probably need to try Beta13 or lower because the API has been changed excessively after Beta13. Contributed modules need some time to catch up.
