Apache Lucene is a full-text search library created by the Apache Software Foundation. Being a full-featured text search, Lucene aims to search a set of text documents for one or more keywords specified by the user. Apache Lucene is an open-source and free program library.

Lucene allows its users to add search capabilities to websites or applications. It takes content and adds it to a full-text index which can then be used to perform queries. This content, consequently, can be ingested from any number of sources, such as a SQL database or even from the website itself. In order to understand how Lucene works, it is important to know that there are various components to it: an index, the documents that it works with and segments. The core of Lucene is the index, which is vital for the search since all documents are stored in it.
