Enum Pooling 

pub enum Pooling {
    Cls,
    Mean,
}

How a BERT model’s per-token outputs are collapsed into one sentence vector. A model is trained with one mode — using the other silently degrades ranking — so it is auto-detected from the repo’s 1_Pooling/config.json, with this as an explicit override.

Variants

Cls

The [CLS] (first) token’s vector. bge is CLS-pooled.

Mean

Masked average of all token vectors. e5/gte/MiniLM/mpnet are mean-pooled.
