Firm footing for building any search experience

For decades, developers have relied on the speed, scale, and relevance of Elasticsearch for building their most important search functionality.


    For developers, by developers

    Choose from a vast set of language clients, implement search, and manage touch points programmatically. Index documents, search and filter, track click-throughs, manage search customizations or engines, and more, all via REST APIs.

  • Future-proof search

    ML & vector search-powered

    With a vector database and natural language processing (NLP) transformer models, developers can unlock the power of AI innovation. Implement semantic search, hybrid ranking, ML tasks, and recommendation engines tailored to customer segments. Add private data to LLMs and generative AI for more relevance and accuracy.


    Highly relevant (and mighty customizable)

    Out of the box, Elastic's relevance models are optimized for real-life search. Use an easy-to-download model for semantic search across domains. Combine vector and textual search with hybrid ranking. Precision tuning, adaptive relevance, synonym sets, weights, and boosts let you tailor results even further.


    Real-time intelligence, actionable insights

    Get complete visibility into user behavior with analytics that highlight what's working, what’s not, and how to make necessary improvements and adjustments.


    Any platform, any data, anywhere

    A variety of ingestion methods — native connectors for databases, connector clients for SaaS productivity apps, web crawler, API, JSON import — let developers index, enrich, and sync data and define schema exactly the way they'd like.


    Built for speed and scale

    Elasticsearch power means you don't have to sacrifice real-time speed as your data and compute volume increase. Build with confidence knowing that performance won’t deteriorate as search data and query volume grow.
