Struct FilteredBm25Executor 

pub struct FilteredBm25Executor<I: InvertedIndex> { /* private fields */ }

A BM25 executor that applies filter pushdown

Implementations

impl<I: InvertedIndex> FilteredBm25Executor<I>

pub fn new(index: Arc<I>) -> Self

Create a new executor

pub fn search( &self, query: &str, k: usize, allowed: &AllowedSet, ) -> Vec<ScoredResult>

Execute a BM25 query with filter pushdown

Algorithm

1. Tokenize query
2. Get posting lists for each term
3. Sort terms by DF (ascending) for early pruning
4. Intersect posting lists with AllowedSet (in DF order)
5. Score only docs in intersection
6. Return top-k
