Experiment Query Parameters Stage

This stage was introduced in Fusion 2.4.

The Experiment Query Parameters query pipeline 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 Experiment query stage selects a variant from a a running experiment and inject its properties into the current PipelineContext.
