Hi,
Quick question, on llama index we have a similarity score when querying the nodes right, is that score mean 0 not similar and 1 mean very similar? In other word, the direction is on the oppisite of Eucladian Distance.
Euclidean Distance: Euclidean distance calculates the straight-line distance between two points in the vector space. Smaller distances indicate greater similarity. This metric is used when the magnitude and direction of vectors are both important.
If yes, then I think we have a problem on the PgVectorStore scoring logic and order.
