GitHub - elastic/elasticsearch-labs: Notebooks & Example Apps for Search & AI Applications with Elasticsearch (original) (raw)

Elasticsearch Examples & Apps

Visit Search Labs for the latest articles and tutorials on using Elasticsearch for search and AI/ML-powered search experiences

This repo contains executable Python notebooks, sample apps, and resources for testing out the Elastic platform:

• Learn how to use Elasticsearch as a vector database to store embeddings, power hybrid and semantic search experiences.
• Build use cases such as retrieval augmented generation (RAG), summarization, and question answering (QA).
• Test Elastic's leading-edge, out-of-the-box capabilities like the Elastic Learned Sparse Encoder and reciprocal rank fusion (RRF), which produce best-in-class results without training or tuning.
• Integrate with projects like OpenAI, Hugging Face, and LangChain, and use Elasticsearch as the backbone of your LLM-powered applications.

Elastic enables all modern search experiences powered by AI/ML.
