Hi - We are having a tree based structure in solr and we are using solr graph
queries to perform some search in our usecases. Example - {! graph from=xx
to=yy} we got a new requirement like we need to search last level nodes based
on some parents in the tree and those last level nodes needs to be used as a
filter again to another query(different core/collection). So the tree was part
of one core where we need to find the last level based on the parent nodes and
these child nodes should be applied as a filter to another core. Rather than
doing a two step approach like fetching the last child first and apply to the
second query. Can we do in a single query by joining these two core/collection?
