What's coming next with Apache Lucene?
06-20, 09:30–09:50 (Europe/Berlin), Kesselhaus

This talk will discuss the ways Apache Lucene might go in the next years. From the perspective of a full-text search engine, it looks like it is feature-complete. So what comes next?

Around Lucene 8 most people thought "There's not much that can be done anymore". In contrast to that, if you look into Apache Lucene's list of new features after each release, you will see mostly 2 new areas of improvements: Vector search and performance improvements.
Is this the end of development? For sure: No! This talk will check how ongoing optimizations in the Java ecosystem might be implemented in Apache Lucene. As example, this will present the new vector incubation module in recent JDKs and how it helps to make indexing and searching much faster starting with Java 20.
