The most obvious use case of that is a weighted graph where the edge attribute is a numerical weight (e.g. in Yonik's example: sort/rank by rating). For me, I'm exploring how to use KB data (Yago, which is basically RDF triples) as part of relevance and to answer questions. These are commonly done in a triple store (RDF engine), but w/ this graph stuff in Solr, I think it could be possible to do in Solr (and quite simply at that), which significantly simplifies the overall system. > > > Joel Bernstein > http://joelsolr.blogspot.com/ > > On Wed, Oct 26, 2016 at 9:39 AM, Grant Ingersoll <gsing...@apache.org> > wrote: > > > The other way to think about is: I want to put labels on the edges.
