Enum SearchArm 

pub enum SearchArm {
    Hybrid,
    Bm25Only,
}

Which retrieval pipeline an eval arm exercises (#686 default-flip decision).

Variants

Hybrid

Full default pipeline: BM25 + dense embeddings + SPLADE + RRF + rerank.

Bm25Only

Pure lexical BM25 — the conservative lower bound of the lean (dense_enabled = false) path, which additionally keeps graph proximity, reranking and SPLADE on top. If pure BM25 already matches hybrid, the real lean path is ≥ that, so flipping the default cannot regress quality.

Trait Implementations

impl Clone for SearchArm

fn clone(&self) -> SearchArm

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SearchArm

impl Debug for SearchArm

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for SearchArm

impl PartialEq for SearchArm

fn eq(&self, other: &SearchArm) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
