License & Support
Free to use — Elastic License 2.0
The Index Server is free to use — including in production and for commercial purposes — under the Elastic License 2.0 (full text). In plain terms:
- You may download, install, copy, and use the software on your own infrastructure, at no cost, for any internal business purpose.
- You may not provide the software to third parties as a hosted or managed service (i.e., resell it as a service).
- You may not remove or alter licensing or copyright notices.
No warranty; limitation of liability
The software is provided "as is", without any warranty or condition of any kind. As far as the law allows, SearchBlox Software, Inc. will not be liable for any damages arising out of the use or nature of the software, under any kind of legal claim. See the license text for the operative terms.
Your data
The software runs entirely on your own infrastructure. Your indexed documents, queries, and vectors never leave your network — SearchBlox does not receive your data. You are responsible for how the software is deployed and secured in your organization, including access control, TLS, and your own compliance with the laws and regulations that apply to your industry and data (privacy, sector rules, export controls).
Third-party components
The server embeds third-party components which are distributed under their own licenses (included with the software bundle); those licenses govern your use of the components and are not modified by the software license. SearchBlox makes no warranty regarding third-party components.
Commercial support
The free software comes without any support obligation. Production support plans — deployment assistance, sizing and scaling guidance, upgrades, and SLAs — are available with the SearchAI platform, which adds enterprise search, RAG pipelines, hybrid + vector search, personalization, and agentic workflows on top of this server — contact SearchBlox support to discuss.
