Better Binary Quantization (BBQ) vs. Product Quantization

Why we chose to spend time working on Better Binary Quantization (BBQ) instead of product quantization in Lucene and elasticsearch.

What is semantic reranking and how to use it?

What is semantic reranking and how to use it?

Introducing the concept of semantic reranking. Learn about the trade-offs using semantic reranking in search and RAG pipelines.

Ready to build state of the art search experiences?

Sufficiently advanced search isn’t achieved with the efforts of one. elasticsearch is powered by data scientists, ML ops, engineers, and many more who are just as passionate about search as your are. Let’s connect and work together to build the magical search experience that will get you the results you want.
