Estimated number of distance calculations

estimated_nodes_visited: usize

Estimated number of nodes to visit

will_overfetch: bool

Whether over-fetching will occur (for filtered queries)

recommendations: Vec<String>

Recommendations for optimization

estimated_duration_ms: f32

Estimated query duration in milliseconds
