@heemin32 The doc team is working through Ingest APIs content gaps. This issue is tracking those gaps. At your availability, will you review and provide your feedback on anything we've missed? Thank you.

1. Enrich data (set up enrich processor, add tutorials (example geolocation, example exact values, example value to a range), enrich policy definition) is not supported in OpenSearch.

2. foreach processor is missing.
