Although they’re jointly developed, Lucene and Solr are actually two different things. Lucene is just a Java library, not a stand alone search engine. Solr is a search engine server built with Lucene as its core.

Lucene was created in 1999 by Doug Cutting, better known as the creator of Apache Hadoop, and has been used both companies like AOL and LinkedIn to power search features.

If you have ever lost your Windows password or If you can’t log in even after trying your twelve passwords, or you’ve inherited a computer complete with password-protected profiles, worry not – you don’t have to do a fresh install of Windows.
