Experiment Query Parameters Stage

The Experiment Query Parameters stage was introduced in Fusion 2.4. This stage is part of Fusion’s Machine Learning framework. It is highly experimental and subject to change.

The Machine Learning framework provides tools to evaluate alternative methods of computing and displaying search results. For example, an experiment may consist of a system which has two or more different query pipelines running, and users are randomly served search results using some variant of the system via instrumented pages that capture user response. In such a system, the Experiement query stage selects a varient from a a running experiment and inject its properties into the current PipelineContext.
