Based upon the open-source Lucene™ project, Solr provides expected full-text search capabilities including phrase and wildcard search. Features that you may not expect include, SQL features like joins, grouping and functions and arithmetic operations.
Solr is used world-wide in extremely large scale environments.


Scalability and fault-tolerance are built right in. Large content and query volumes are easily handled through Solr's sharding. Multiple modes of replication allow for almost any scenario to be handled.
Solr is flexible and adaptable to address your needs with simple configuration.


Need up to the minute information? No worries, Solr indexing is real-time capable.
Solr capabilities can be extended through plugins – both query and index time behaviours can be extended.
