 # Elasticsearch
 
-This section contains reference information for {{es}} and index management features.
+{{es}} is a distributed search and analytics engine, scalable data store, and vector database built on Apache Lucene. It’s optimized for speed and relevance on production-scale workloads. Use Elasticsearch to search, index, store, and analyze data of all shapes and sizes in near real time.
 
-To learn more about {{es}} features and how to get started, refer to the [{{es}}](docs-content://solutions/search.md) documentation.
