We're looking to sustain (and evolve!) a search and analytics suite for the multitude of businesses who are dependent on the rights granted by the original, [Apache v2.0 License](LICENSE.txt). ## Project Resources * [Project Website](https://opensearch.org/) * [Downloads](https://opensearch.org/downloads.html) * [Documentation](https://opensearch.org/docs/) * Need help?
