Node2vec embeddings not used in query phase?

[Kieran-Mg1]

It's stated in phase 4 of the indexing dataflow that node2vec embeddings act as an "additional vector-space in which to search for related concepts during our query phase". However, I can't see where the node embeddings are saved, nor where they are used in the (local) query stage. As far as I can tell they are only used in the UMAP plot. Am I missing something?

P.S. this is not related to settings.yaml and embed_graph set to "enabled", this is about how the node2vec embeddings are utilised.
