The most extensive search toolkit for 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.

With natural language processing (NLP) models and vector search, developers can unlock the power of semantic search, named entity recognition (NER), text classification, sentiment analysis, and recommendation engines tailored to customer segments.

Out of the box, Elastic's relevance models are optimized for real-life search. Precision tuning, adaptive relevance, synonym sets, and weights and boosts let you personalize even further.

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

A variety of ingestion methods — web crawler, API, JSON import — let developers index and sync data and define schema exactly the way they'd like.

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.
