OPEN SOURCE SEARCH, ANALYTICS, AND AI PLATFORM

Elasticsearch

Elasticsearch is an open source, distributed search and analytics engine built for speed, scale, and AI applications. As a retrieval platform, it stores structured, unstructured, and vector data in real time — delivering fast hybrid and vector search, powering observability and security analytics, and enabling AI-driven applications with high performance, accuracy, and relevance.

What makes Elasticsearch a search, analytics, and AI powerhouse?

It's because Elasticsearch is a …

Datastore
Store everything. Search anything. Structured, unstructured, and vectors — all under one roof with efficient columnar storage. For us, data is just data.
Vector database
Semantic meets syntax. Text, image, and multi-modal vectors — all in one API. Billions of embeddings, deployable anywhere you need.
Analytics engine
Think faster. Act smarter. Real-time data analytics move with speed to aggregate and transform even high-cardinality data instantly.
Search engine
Shockingly relevant. Full-text, filters, vectors, and scoring. Real-time search and precision at scale — built for developers, loved by data.
Geospatial engine
Put your data on the map. Literally. Search it, shape it, and show it off with geo-distance, polygons, and hexagonal spatial analytics.

Serious capabilities. Surprisingly simple.

Lightning-fast search performance
Millisecond-latency search, powered by Lucene. Instant answers, no matter how fast data moves.
Build search applications

Global distributed scalability
Scale effortlessly. Elasticsearch autoscales, rebalances, replicates, and powers through petabytes — with no downtime and no drama. Need global reach? Cross-cluster search delivers federated search without the fuss.

Versatile data and use case flexibility
Text? Timestamps? Vectors? Yes. One platform to do it all. From search to observability to security, Elasticsearch is built once and reused everywhere. Developed for whatever else your data dreams up.

Advanced search and relevance
Fuzzy, semantic, or precise — Elasticsearch finds significance in your data. Full-text search, vector search, and hybrid search with filters, ranking, and reranking for unmatched relevance.
Smart storage and deep search
Elasticsearch delivers performant, searchable, cost-effective data storage. From hot tier on local disks to searchable snapshots on object storage, get speed and savings — no compromises needed.
Connected and integrated
Built-in connectors, common schemas, and open standards. Ingest fast with APIs, clients, and pipelines. Elasticsearch meets your data where it lives to connect, ship, analyze, and search all data types.

From bare metal to serverless. It's your call.

From a laptop to a hundred‑node cluster, Elasticsearch works the same everywhere. On‑premises, in the cloud, or across clouds — we'll be there.

Store any data

Securely store, analyze, and scale all data types — structured, unstructured, time-series, logs, events, geospatial, vectors, and more. No need to move data to a central location or refactor data to fit.

POST /my-index/_doc/1
{ "timestamp": "2025-02-19T14:30:00Z", "log_level": "ERROR", "message": "Unauthorized access attempt detected", "event_id": "abc123xyz", "user": { "id": "user_456", "username": "jdoe", "ip_address": "192.168.1.100" }, "geo": { "lat": 39.7392, "lon": -104.9903, "city": "Denver", "region": "Colorado", "country": "US" }, "http": { "method": "POST", "url": "/admin/login", "status_code": 401, "user_agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64)" }, "security": { "alert_type": "Failed Login", "severity": "high", "action_taken": "Blocked IP", "detection_engine": "SIEM" }, "server": { "hostname": "webserver-01", "environment": "production" } } }

Semantic search
Keyword-based search falls short when users need results based on meaning, not just exact matches. Elasticsearch enables semantic search with dense and sparse vectors, hybrid retrieval, and advanced relevance tuning — powering AI-driven applications that understand intent and context for more accurate results.
FROM search-movies | EVAL len = length(semantic_title) | EVAL semantic_title = to_upper(semantic_title) | KEEP semantic_title, len | SORT len DESC
Rerank search
Returning relevant results isn't just about matching terms — it's about ranking what matters most. Elasticsearch enhances search quality with reranking techniques, using vector search, hybrid retrieval, and machine learning to refine and prioritize the best results for each query.
FROM my-index* | EVAL distance = ST_DISTANCE(TO_GEOPOINT(location, city_location)) | KEEP timestamp, user.username, location, distance, city_location | SORT distance ASC

Geospatial search & analytics

Scaling geospatial search is challenging with large datasets and real-time location updates. Elasticsearch enables fast geospatial search, mapping, and geo-hex analytics while optimizing query performance at scale.

FROM security-logs
| LOOKUP JOIN envs_lkp ON clientip
| WHERE environment IS NOT NULL
| KEEP @timestamp, clientip, environment
| EVAL env = CONCAT(environment, " Environment")
| LOOKUP JOIN blocked_lkp ON clientip
| LOOKUP JOIN emp_lkp ON clientip
| WHERE ST_INTERSECTS(
    "POLYGON((109.4 18.1, 109.6 18.1, 109.6 18.3, 109.4 18.3, 109.4 18.1))"::geo_shape,
    client_location
  )
| STATS COUNT(action) BY emp_no, first_name

Time series analysis
Monitoring modern applications and infrastructure requires real-time insights across signals, telemetry, logs, metrics, and traces. Elasticsearch powers observability solutions with scalable data ingestion, fast search, and advanced analytics — helping teams detect issues, troubleshoot performance, and optimize system health efficiently.
FROM my-index* | WHERE http.status_code >= 500 | STATS failure_count = COUNT(*) BY server.hostname | SORT failure_count DESC | KEEP server.hostname, failure_count
Threat hunting
Detecting and investigating security threats requires analyzing massive volumes of logs in real time. Elasticsearch powers SIEM solutions with high-speed log ingestion, scalable AI threat detection, and fast search across structured and unstructured security data so teams can identify anomalies and respond to threats faster.
FROM my-index* | WHERE log_level == "ERROR" OR security.severity == "high" | SORT timestamp DESC | KEEP timestamp, user.username, message, security.alert_type, security.severity, http.status_code

POST /my-index/_doc/1
{ "timestamp": "2025-02-19T14:30:00Z", "log_level": "ERROR", "message": "Unauthorized access attempt detected", "event_id": "abc123xyz", "user": { "id": "user_456", "username": "jdoe", "ip_address": "192.168.1.100" }, "geo": { "lat": 39.7392, "lon": -104.9903, "city": "Denver", "region": "Colorado", "country": "US" }, "http": { "method": "POST", "url": "/admin/login", "status_code": 401, "user_agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64)" }, "security": { "alert_type": "Failed Login", "severity": "high", "action_taken": "Blocked IP", "detection_engine": "SIEM" }, "server": { "hostname": "webserver-01", "environment": "production" } } }
