Elasticsearch is a distributed, RESTful search and analytics engine capable of addressing a growing number of use cases. As the heart of the Elastic Stack, it centrally stores your data for lightning fast search, fine‑tuned relevancy, and powerful analytics that scale with ease.

In Elasticsearch 8.2, aggregate data up to 80x faster with the random sampler aggregation, and now search for nearest doc with filter support for ANN.
Scalability
Go from prototype to production seamlessly; you talk to Elasticsearch running on a single node the same way you would in a 300-node cluster.
It scales horizontally to handle kajillions of events per second, while automatically managing how indices and queries are distributed across the cluster for oh-so-smooth operations.
Relevance
Rank your search results based on a variety of factors — from term frequency or recency to popularity and beyond. Mix and match these along with functions to fine tune how your results show up to your users.
And because most of our users are human, Elasticsearch is equipped to handle human mistakes including complexities like typos.
Resiliency
Hardware rebels. Networks partition. Elasticsearch detects failures to keep your cluster (and your data) safe and available. With cross-cluster replication, a secondary cluster can spring into action as a hot backup. Elasticsearch operates in a distributed environment designed from the ground up for perpetual peace of mind.
FLEXIBILITY
Data is constantly evolving, and it can become expensive to store and search all of it. With Elasticsearch you can balance performance and cost. Store data locally for fast queries or remotely on low-cost S3 for unlimited data. With runtime fields, you can also quickly onboard your data — and adapt to changes.
Use Cases
Numbers, text, geo, structured, unstructured. All data types are welcome. Full-text search just scratches the surface of how companies around the world are relying on Elasticsearch to solve a variety of challenges. See a full list of solutions built directly on the Elastic Stack.
