Hi, Thanks for the responses! For Patrick's question, right now in faceting we don't have any good way to AND between two fields. I think the original hyper rectangle issue has a good example of a use case: https://issues.apache.org/jira/browse/LUCENE-10274.
As for Robert's point, this feature would also allow us to use MultiRangeQuery in IndexOrDocValuesQuery, but MultiRangeQuery is itself in the sandbox module so I'm assuming that's a pretty exotic use case as well. I personally have no issues using BinaryDocValues for this, I was just wondering if it would be better to create a dedicated doc values, but it seems that is not that case.
