Features
A high quality search experience is as critical to your site's perceived value as the site design and the content itself. Acquia Search is a plug-and-play service available in the Acquia Network that delivers dynamic search navigation tools to your visitors in familiar, easy to use components on your website.
Based on the powerful Lucene and Solr technologies from the Apache project, Acquia Search creates a rich index of your site's content to facilitate search-based navigation. When visitors search your site, Acquia Search presents them with dynamically-created filters so they can drill into results based on date, relevancy, author, tags, content type, or other attributes.

Faster performance - improve site response times and lower abandon rates by offering a faster search experience than Drupal's built-in search
Why Acquia Search over Apache Solr?
Apache Lucene and Apache Solr can be complex to get running and to maintain. Acquia solves the complexity problem by offering Solr search as a service in the Acquia Network.
