Fields

root: LogicalNode

The root logical node.

index_type: IndexType

Which index backend to use.

use_hybrid: bool

Whether to run hybrid retrieval.

pre_filter: bool

Whether to apply metadata filter BEFORE the vector scan.

filter_predicate: Option<String>

The scalar predicate to apply (serialised JSON), if any.

estimated_cost: f32

Estimated cost in arbitrary units.

candidate_k: usize

How many dense candidates to fetch (output_k * oversample).

output_k: usize

Final k — how many results to return after filtering and sorting.

output_columns: Vec<String>

Columns to project onto results. Empty means SELECT * (keep everything).
