This module provides a Solr backend for the Search API module.
The backend uses, like the popular Apache Solr Search Integration module, Apache Solr servers for indexing and searching content. It has great performance, is suitable even for use on large commercial websites and supports facets and multi-index searches.
- The Search API module, of course.
- An Apache Solr server which can be individually configured (or has a configuration compatible with this module).
