OpenSearch

OpenSearch is an open source search and observability suite that brings order to unstructured data at scale. It is the engine underneath self-managed search and log analytics deployments, and the repository here holds that engine rather than the tutorials around it.

The README is deliberately a signpost. Downloads, installation instructions and the full feature documentation live on the project website and documentation site, while forums and a Slack workspace handle questions. Guides inside the repository cover contributing, maintainer and admin responsibilities, release management and testing.

A handful of facts matter before adopting it.

• License: Apache version 2.0, with copyright held by the OpenSearch Contributors.
• Lineage: the codebase includes certain Apache-licensed Elasticsearch code from Elasticsearch B.V., which is not the source of the remaining code.
• Stewardship: OpenSearch is a registered trademark of LF Projects, LLC, and project health is reported through Linux Foundation insights.
• Security reporting: potential vulnerabilities go by email to the OpenSearch security team rather than into a public issue.
• Community conduct: a code of conduct sets expectations for everyone taking part, with a contact address for questions.

Because the practical material sits outside the source tree, teams evaluating OpenSearch should start from the documentation site and the downloads page, then use the forums or Slack for the operational questions that follow.
