Updating lucene index
Lucene is an Open Source, mature and high-performance Java search engine.
I started this project because I needed a tool like this.When you’re familiar with Hibernate Search and Lucene, you should also have a look at the other supported attribute in a full-text search query.But before you can do that, you might need to create the initial index based on the data already stored in your database.Hibernate Search manages the Lucene index and keeps it in sync when you change indexed entities.That’s great when you start with an empty database. If you’re working with an existing database, you need to add the existing records to your Lucene index.The Explanation tree shows how various term matches and normalizations resulted in the final document score for the current query.
Please note how the fuzzy query expanded the term "book" into "books" (and, not visible here, "bookstore", "bookstores", etc...), adjusting the weight of this hit.
I recommend using the in the beginning, which is also used by default.
It stores the Lucene indexes in the file system which allows you to easily inspect them and get a better understanding of your system.

Full-text search has become a common requirement for modern enterprise applications, and there are several good implementations available, like Apache Lucene and Elasticsearch.
