Configuration for hierarchical gist reranking.

Fields

relevance_weight: f32

Weight for original relevance score (0.0-1.0)

density_weight: f32

Weight for gist density score (0.0-1.0)

gist_query_similarity_weight: f32

Weight for gist-to-query similarity (0.0-1.0, CogniRank)

recency_weight: f32

Weight for recency score (0.0-1.0)

diversity_lambda: f32

Lambda for MMR diversity (0.0-1.0) 1.0 = relevance only, 0.0 = diversity only

max_key_points: usize

Maximum key points to extract per episode

min_density_threshold: f32

Minimum density threshold to include in results

recency_half_life_days: f32

Half-life for recency decay in days
