Comparing OpenSearch results with results from the plugin

The Amazon Personalize Search Ranking plugin rearranges search results based on both the ranking from Amazon Personalize and the ranking from OpenSearch. The way that the plugin re-ranks the results depends on how you configured the personalized_search_ranking response processor in your pipelines.

To understand how results are re-ranked, you can run queries with and without personalization, and compare the results.
