Overview
Research summary
Elasticsearch indexes documents for text search, filtering, analytics and vector similarity queries. AI applications can combine lexical and semantic retrieval to provide context for generation while retaining existing search infrastructure. The licensing scope is not uniform: eligible free source portions offer AGPLv3, SSPL or Elastic License options, while the default distribution and paid features use Elastic License 2.0. Elastic Cloud is a separate managed service. This entry describes the search engine, not the entire Elastic observability and security product portfolio.
