Search reranker healthcheck not ok

The Search API uses machine learning to rank search results based on analytics data. If this alert fires, something has gone wrong with that process and we’re serving results as they were ordered by elasticsearch.

Unlike the other healthcheck failures, this does not mean that Search API is serving errors. Only that it is serving potentially worse results.

The machine learning model is hosted in Amazon SageMaker.

How do I investigate this?
