Ok, so it wasn't actually that difficult to find out what was going on :)
https://github.com/kzwang/elasticsearch-image/blob/master/src/main/java/org/elasticsearch/index/query/image/AbstractImageScorer.java
I don't really understand the motivation for the following bit of code, is
there something bad about returning the Lire score? Could you possibly
explain please?
if (Float.compare(distance, 1.0f) <= 0) { // distance less than 1, consider
as same image
score = 2f - distance;
} else {
score = 1 / distance;
}
Thank you,
V
