Hi all, I've started to look at image similarity. For each image in documents I have a couple of vectors that represent the color and shape similarity.
As pointer to begin a colleague suggested me to start with this project: https://github.com/moshebla/solr-vector-scoring but the project seems old and not maintained... On the other hand, looking at Solr Documentation I see there is support for dot product and cosine Similarity https://lucene.apache.org/solr/guide/7_5/vector-math.html#dot-product-and-cosine-similarity So Solr has the capability to calculate the similarity between two vectors. But it is not clear how to use this native feature when searching. Am I missing something? Any help or even suggestion would be appreciated. Best regards, Vincenzo -- Vincenzo D'Amore
