This is a question about "isA?" We want to know if M isA B isA?(M,B)
For some M, one might be able to look into M to see its type or which class(es) for which it is a subClass. We're talking taxonomic queries now. But, for some M, one might need to ripple up the "transitive closure", looking at all the super classes, etc, recursively. It seems unreasonable to do that over HTTP; it seems more reasonable to grab a core and write a custom isA query handler. But, how do you do that in a SolrCloud? Really curious... Many thanks in advance for ideas. Jack
