As a follow up, is it correct that the parent child grouping is on it’s own segment? And would this segment have it’s own LeafReader that I could identify and access. I think this might solve my problem. -scott

In our older implementation we had custom filtering/scoring mechanism that allowed us to query our grouped documents as a single entity. In particular, this allowed us to query documents that had the same field name and different values as a single entity. We’d like to be able to to this with the new ToParentBlockJoinQuery mechanism. Is there any part of the api that would allow us to query two documents with different values for the same field (as in a boolean query with two Occur. MUST designations) and return a parent document that contained these two values while at the same time returning no other parents that had one of the other values? (Which would be the case with a boolean query with two or more Occur.SHOULD designations) Performance is a consideration here. Thanks, Scott
