About Elasticsearch

Elasticsearch is a distributed search and analytics engine that supports vector search alongside traditional full-text search capabilities. It enables hybrid search scenarios combining semantic similarity and keyword search. Elasticsearch is widely used in production environments for applications such as search engines, log analysis, and AI-powered search. Its distributed architecture provides scalability, reliability, and performance for large datasets.
