pub struct TextRelevanceObjective;Expand description
Scores a candidate by BM25/FTS relevance.
Returns text_score unchanged, or 0.0 when the field is absent.

impl Objective<RetrievalCandidate> for TextRelevanceObjective
Source§fn score(
&self,
candidate: &RetrievalCandidate,
_context: &ObjectiveContext,
) -> f64
fn score( &self, candidate: &RetrievalCandidate, _context: &ObjectiveContext, ) -> f64
Evaluate a single candidate.
Source§fn precision(&self, _candidate: &T, _context: &ObjectiveContext) -> f64
fn precision(&self, _candidate: &T, _context: &ObjectiveContext) -> f64
Precision (inverse variance) of the score estimate; default 1.0 (fully trusted).
Source§fn passes_score(&self, score: f64, context: &ObjectiveContext) -> bool
fn passes_score(&self, score: f64, context: &ObjectiveContext) -> bool
Check if a score passes the threshold; non-finite scores never pass.
Source§fn passes(&self, candidate: &T, context: &ObjectiveContext) -> bool
fn passes(&self, candidate: &T, context: &ObjectiveContext) -> bool
Check if a candidate passes the threshold.
Source§fn batch_score(
&self,
candidates: &[T],
context: &ObjectiveContext,
) -> Vec<(usize, f64)>
fn batch_score( &self, candidates: &[T], context: &ObjectiveContext, ) -> Vec<(usize, f64)>
Score a batch of candidates and return passing
(index, score) pairs.Source§fn select<'a>(
&self,
candidates: &'a [T],
context: &ObjectiveContext,
) -> Vec<Selection<&'a T>>
fn select<'a>( &self, candidates: &'a [T], context: &ObjectiveContext, ) -> Vec<Selection<&'a T>>
Select all passing candidates in score-descending order.
Source§fn select_top<'a>(
&self,
candidates: &'a [T],
n: usize,
context: &ObjectiveContext,
) -> Vec<Selection<&'a T>>
fn select_top<'a>( &self, candidates: &'a [T], n: usize, context: &ObjectiveContext, ) -> Vec<Selection<&'a T>>
Select the top N candidates by precision-weighted score.
