About Apache Solr
Apache Solr is an open source search platform built upon a Java library called Lucene
Solr is a standalone enterprise search server with a REST-like API. You put documents in it (called indexing) via JSON, XML, CSV or binary over HTTP. You query it via HTTP GET and receive JSON, XML, CSV or binary results.
