------------------------------------
Summary: Move Points from a visitor API to a custor-style API?
Key: LUCENE-9619
URL: https://issues.apache.org/jira/browse/LUCENE-9619
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
Points' visitor API work well but there are a couple things we could make
better if we moved to a cursor API, e.g.
- Term queries could return a DocIdSetIterator without having to materialize a
BitSet.
- Nearest-neighbor search could work on top of the regular API instead of
casting to BKDReader

- We could optimize counting the number of matches of a query by adding the
number of points in a leaf without visiting documents where there are no
deleted documents and a leaf fully matches the query.
