Hi, thanks a lot for the feedback. There are a lot of applications where indexed relationships will provide a speed benefit, but just to a limit. This advantage of sparse properties on a lot of edges ( I.e. 100 relationships with a property - as opposed to 1000 relationships without ) holds its b

Hi, how do you guys expect indexing for relationships to work? Would it be an index just as for nodes... or per node? I often hear that it'd speed up traversals if a node has many, many neighbours. But if the relationship index would be for the entire graph (not per node) that wouldn't really help

A side comment, since I think indexing relationships with lucene might be good, but think there might be alternatives for your current example. You said that the relationship property is a float from 0 to 1, so you cannot use relationship types, but actually, when you consider that any index is us
