LinkedIn has just open-sourced the technology behind IndexTank under the Apache 2.0 License.
The IndexTank technology has three separate toolsets:
- IndexEngine - A real-time fulltext search-and-indexing system designed to separate relevance signals from document text
- API - A RESTful interface that handles authentication, validation, and communication with the IndexEngine(s)
- Nebulizer - Multitenant framework to host and manage an unlimited number of indexes running over a layer of Infrastructure-as-a-Service

An example of IndexTank in action is, Reddit, which runs on IndexEngine and the API.
They have the
IndexTank Engine and
IndexTank Service code published at Github, and created a
LinkedIn Group to support it.
