The Elasticsearch platform is equipped with machine learning and AI solutions, including a semantic search model: the Elastic Learned Sparse EncodeR — or ELSER. This NLP model is trained by Elastic to enable semantic search in an easy-to-deploy tool. Elasticsearch securely stores your data for fast search, fine‑tuned relevance, and powerful analytics that scale efficiently. Elasticsearch is the central component of the Elastic Stack, a set of free and open tools for data ingestion, enrichment, storage, analysis, and visualization. Learn more about Elasticsearch
