1 What Is Solr?

Solr is the popular, blazing fast open source enterprise search platform from the Apache

Lucene project. Its major features include powerful full-text search, hit highlighting, faceted

search, dynamic clustering, database integration, rich document (e.g., Word, PDF) handling,

and geospatial search. Solr is highly scalable, providing distributed search and index

replication, and it powers the search and navigation features of many of the world's largest

plugin architecture when more advanced customization is required.

See the complete feature list for more details.

For more information about Solr, please see the Solr wiki.
