Enum RetrievalMode 

#[non_exhaustive]
pub enum RetrievalMode {
    Dense,
    Sparse,
    Hybrid {
        alpha: f32,
    },
}

The retrieval mode (dense, sparse, or hybrid).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Dense

Dense vector retrieval (default).

Sparse

Sparse keyword-based retrieval (e.g., BM25).

Hybrid

Hybrid retrieval combining dense and sparse.

Fields

alpha: f32

Weight for dense retrieval. 1.0 = pure dense, 0.0 = pure sparse.
