Function from_ids

nodedb/src/query/bitmap.rs:10–12

Build a roaring bitmap from a set of document IDs. Used for pre-filtering during HNSW vector search: the bitmap indicates which document IDs satisfy metadata predicates, so the vector engine can skip non-matching candidates during traversal.

(ids: impl IntoIterator<Item = u32>)

/// which document IDs satisfy metadata predicates, so the vector engine
/// can skip non-matching candidates during traversal.

    ids.into_iter().collect()
}

/// Intersect two bitmaps (AND). Used to combine multiple filter predicates.
