The search revolution is finally available to anyone with a Drupal site. By connecting Drupal to a Solr search backend, new possibilities arise for how to structure sites, discover content, and keep your visitors coming back. Acquia provides a Solr search web service that greatly increases search functionality in your Drupal site, including the following:

* Faceted Search
* Content Recommendations
* Spell Checking
* Highlighting
* Phonetic search

This is a very important topic, and represents a major step in Drupal's evolution.
