On: Solr’s Dense Vector Search for indexing and searching dense numerical vectors

You can fit 1M vectors in the free tier of www.pinecone.io if you want to experiment. I'm not sure how fast having that many query vectors would be. (I'm a happy Pinecone customer, but only use a single query vector.)

Huh, at one point you could have multiple queries, but it looks like that is deprecated now.

So maybe it wouldn't work for you use case.
