I enjoyed Berlin Buzzwords very much, always a pleasure to catch up with everyone in person. Here is my talk with @jpountz on shipping Lucene 10: youtu.be/GRhzgCEL_ac?si… .
A realistic, honest and quite non-partisan comparison, admitting that we can always learn to do better:those publishing benchmarks with a lot of marketing spin should learn from this post.
Someone asked me for my opinion on the Vespa vs. Elasticsearch performance comparison today at Berlin Buzzwords, so I gave it a try: jpountz.github.io/2025/06/17/ana…
I'm glad to share that Luca Cavanna and I will be speaking about the #Lucene 10.0 release at Berlin Buzzwords in June.
Something a little different from my typical blogs. This line of code in Apache Lucene took me 3 days to write. For fixing bugs, it's about the journey, not necessarily the destination. elastic.co/search-labs/bl…
Apache Lucene 10.1.0 released, all set for a little break lists.apache.org/thread/xtt5vbv…
Hear hear: Elastic Cloud Serverless is on Lucene 10.0 now for 24 hours, just two weeks after Lucene 10.0 was officially released. What an achievement, and what a team!!!
Speechless, shocked about the death of Luca Salvadori. You had so much more wins in front of you, in life, on track and on road. You'll be sorely missed.
Now that the few post-merge failures are fixed, time to take a minute to celebrate the achievement: Lucene 10 will support decoupling search concurrency from the index's segment geometry. Still work to do, but a great step forward: github.com/apache/lucene/…
Gotta brag on my teammates. Autoscaling is incredibly difficult to get right. However, we are making steps in the right direction. @elastic with zero systems management is pretty neato ;) elastic.co/search-labs/bl…
Congrats to @benwtrent on joining the Apache Lucene PMC. Very well deserved!!! Thanks for all the great work.
I'm pleased announce that we released #Apache #Lucene 9.9.0 today. Lots of great goodies and amazing performance improvements. lucene.apache.org/core/9_9_0/cha… lists.apache.org/thread/t0ypmjz…

From Saussure's theory of language to dense vectors & nearest neighbors: part hands-on demonstration of semantic search in Elasticsearch, part explanation of text embeddings: nb.karmi.cz/semantic-searc…. #NLP #Elasticsearch #huggingface
My team have two great features for @elastic vector search! In 8.7: search multiple vector fields & create embeddings with a ML model in a single API call! Semantic search achievement unlocked! elastic.co/blog/whats-new…
Lucene 9.5.0 release done and dusted, GPG I don't fear you!
