Response Shuffle Stage

This is a response rewriting stage that helps "de-bias" results by shuffling the top N results randomly. Since most users click on result #1 before #2, this stage is helpful for distributing clicks more evenly among the top N results. This stage must be used after the Solr Query stage in your pipeline.

This stage is especially useful when combined with experiments, where a small percentage of traffic is given shuffled results to minimize position bias when using click signals for ranking. The Response Pairwise Swap stage provides an another method for minimizing this bias.

Configuration

Tip
When entering configuration values in the UI, use unescaped characters, such as \t for the tab character. When entering configuration values in the API, use escaped characters, such as \\t for the tab character.
