Hello I've been looking at the BlockJoinQuery in Lucene 3.4.0 and would like to clarify my understanding.
Suppose we have a parent document that we index with (say) 4 child documents. My understanding is that these go in as an atomic unit and allows us to query and join across the documents. Now what say I wanted to update one of the child documents (only). If the child document was update with a standard update, I presume the join to the parent is broken. If I update using a Collection, is it necessary to reindex all of the documents (4 children + pareent). And finally, if I updated one child using a collection with the parent, would both of these documents require reindexing and loose their affinity with other children ? Thanks, C,
