The “collapse” feature is used to remove duplicate results, while “search after” is used for pagination. OpenSearch doesn’t support using these two features together. To resolve this issue, you can either remove the “collapse” feature from your query if removing duplicates is not necessary, or implement pagination manually by using the “from” and “size” parameters instead of “search after”.
