Query: Lucene best practices, distilled

Albeit outdated, 'Lucene in Action' remains a must read for anyone who's looking for a fast and scalable solution for a full-text indexing and search solution. Instead of stumbling through the API documentation all by yourself, the authors provide a high-level overview of the core components of the Lucene API, how to extend them, and best practices associated with each component.For our application, we've adopted Solr, which abstracts the majority of Lucene API's, but the contents of this book have proven to be invaluable when it came to initial setup and quickly bringing our development team up to speed on the internals and best practices of Lucene.
