--- title: Elasticsearch documentation hub description: Elasticsearch documentation. Index, search, and analyze data at any scale. Run it as a managed service or in your own environment. url: https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/7964/products/elasticsearch products: - Elasticsearch --- # Elasticsearch documentation hub The distributed search and analytics engine at the heart of the Elastic platform. Index, search, and analyze data at any scale, build semantic and vector search experiences, and power applications. Run it as a managed service or in your own environment. - [Get started](#get-started) - [What's new](#whats-new) - [Explore Elasticsearch docs](#explore) ## Get started in 3 steps Start a local development environment or a free Elastic Cloud trial, then run your first queries. 1. Run Elasticsearch - Run locally: Spin up Elasticsearch on your machine for development with `start-local`. `curl -fsSL https://elastic.co/start-local | sh` - Try on Cloud: Start a free Elastic Cloud trial. No local setup needed. [Start a free trial](https://cloud.elastic.co/registration) 2. [Ingest your data into Elasticsearch](https://docs-v3-preview.elastic.dev/manage-data/ingest) Send documents to Elasticsearch using the APIs, ingest pipelines, connectors, or a language client. 3. [Search your data](https://docs-v3-preview.elastic.dev/solutions/search/querying-for-search) Build queries to find, rank, and analyze your documents. ## What's new in Elasticsearch Highlights from the latest Elasticsearch release. - [Release notes](https://docs-v3-preview.elastic.dev/elastic/elasticsearch/tree/main/release-notes) - [Columnar index mode](https://docs-v3-preview.elastic.dev/manage-data/data-store/columnar) (9.5, Storage) Store each field once in a column store, with no inverted index by default, for a smaller footprint. Technical preview. - [VectorDB index mode](/solutions/search/vector#vector-index-mode) (9.5, Vector search) Apply vector-search defaults with a single index setting. - [Native Prometheus and PromQL](https://docs-v3-preview.elastic.dev/elastic/elasticsearch/tree/main/reference/query-languages/promql) (9.5, Metrics) Query Prometheus metrics with PromQL in Elasticsearch, generally available. - [DLM frozen tier](https://docs-v3-preview.elastic.dev/manage-data/lifecycle/data-stream/dlm-searchable-snapshots) (9.5, Data lifecycle) Move aging data stream backing indices to the frozen tier as searchable snapshots, without an ILM policy. - [Flattened fields in ES|QL](https://docs-v3-preview.elastic.dev/elastic/elasticsearch/tree/main/reference/elasticsearch/mapping-reference/flattened) (9.5, ES|QL) Query flattened fields and extract sub-fields with FIELD_EXTRACT.
