Expand description

Info for MaxScore-optimizable sparse term queries

Fields§

§field: Field

Sparse vector field

§dim_id: u32

Dimension ID in the sparse vector

§weight: f32

Query weight for this dimension

§candidate: bool

Whether this term participates in candidate generation. BMP/LSP uses the pruned subset for maximum-grid traversal, then scores candidates with every term retained in this decomposition.

§heap_factor: f32

MaxScore heap factor (1.0 = exact, lower = approximate)

§combiner: MultiValueCombiner

Multi-value combiner for ordinal deduplication

§over_fetch_factor: f32

Multiplier on executor limit to compensate for ordinal deduplication (1.0 = exact, 2.0 = fetch 2x then combine down)

§lsp_gamma: Option<usize>

LSP/0 γ. None is depth-derived; Some(0) is exhaustive.
