Why a fact matched and how it was adjusted.

Fields

retrieved: bool

False when the fact was not among the ranked candidates for the query (explain still reports its terms, validity and chain).

rank: Option<usize>

1-based position among the ranked candidates, after the recency policy.

lexical_score: Option<f64>

semantic_score: Option<f64>

retrieval_score: Option<f64>

The fused document search score before the recency policy.

lexical_weight: f64

semantic_weight: f64

fusion: String

matched_terms: Vec<String>

Query words that match the fact’s text (after stemming).

recency_factor: f64

The recency policy’s multiplier; 1 when none is configured.

historical_factor: f64

The multiplier for a non-current fact (historicalWeight); 1 for a current one.

final_score: Option<f64>

status: FactStatus

as_of: Millis

known_at: Option<Millis>

valid_from: Option<Millis>

valid_to: Option<Millis>

within_validity: bool

chain: Vec<ChainLink>
