Fields

session_id: u64

Unique identifier for this session.

original_query: Vec<f32>

The query vector supplied when the session was created.

current_query: Vec<f32>

The query vector after the most recent Rocchio update (or equal to original_query when no rounds have been applied yet).

rounds: u32

Number of times SemanticRelevanceFeedback::apply_rocchio has been called successfully for this session.

feedback_items: Vec<FeedbackItem>
