> The key issue is document collection. Right now, the `topK` is limited to only `topK` children documents. Really, what you want is the `topK` parent documents based on children scores. Just curious, has there been any progress with multi-value vector field support? Elasticsearch seem to support the idea of using the "block join" approach as outlined in this blog post from a couple of weeks ago: https://www.elastic.co/search-labs/blog/articles/chunking-via-ingest-pipelines, although from what I can see, it will suffer from the same issue @benwtrent mentions where the topK will be applied to child documents. -- This is an automated message from the Apache Git Service.
