Struct TopKCollector 

pub struct TopKCollector { /* private fields */ }

Collector for top-k results

Implementations

impl TopKCollector

pub fn new(k: usize) -> Self

pub fn with_positions(k: usize) -> Self

Create a collector that also collects positions

pub fn total_seen(&self) -> u32

Get the total number of documents seen (scored) by this collector

pub fn into_sorted_results(self) -> Vec<SearchResult>

pub fn into_results_with_count(self) -> (Vec<SearchResult>, u32)

Consume collector and return (sorted_results, total_seen)

Trait Implementations

impl Collector for TopKCollector

fn collect( &mut self, doc_id: DocId, score: Score, positions: &[(u32, Vec<ScoredPosition>)], )

Called for each matching document positions: Vec of (field_id, scored_positions)

fn would_collect(&self, doc_id: DocId, score: Score) -> bool

Whether this score can enter the collector’s retained result set.

fn collect_owned( &mut self, doc_id: DocId, score: Score, positions: MatchedPositions, )

Collect already-owned positions. Position-aware collectors can override this to move the nested vectors instead of cloning them.

fn needs_positions(&self) -> bool

Whether this collector needs position information
