Apache Solr is an open source text search server. It is based on the Apache Lucene search libraries. Solr does full-text search, highlight the hits, near real-time indexing.

It has an extremely scalable search infrastructure that provides replication, load-balanced search query, and automatic failover. This can get the input data that needs to be indexed for searching from various sources including information from a database. You can use HTTP/XML, JASON APIs provided by Apache Solr and write application code in any programming language.
