URL: https://github.com/apache/lucene/pull/14680
Originally (before optimistic KNN query):
```
recall latency(ms) nDoc topK fanout maxConn beamWidth quantized
visited selectivity filterType vec_disk(MB) vec_RAM(MB) indexType
0.693 7.374 1000000 100 50 16 50 no
3753 0.05 pre-filter 0.000 0.000 HNSW
0.705 7.752 1000000 100 100 16 50 no
4680 0.05 pre-filter 0.000 0.000 HNSW
0.764 13.086 1000000 100 250 16 50 no
6307 0.05 pre-filter 0.000 0.000 HNSW
```
Mainline (filtering broken):
```
recall latency(ms) nDoc topK fanout maxConn beamWidth quantized
index(s) index_docs/s num_segments index_size(MB) vec_disk(MB) vec_RAM(MB)
indexType
0.894 31.510 1000000 100 50 16 50 no
0.00 Infinity 0 0.00 0.000 0.000
HNSW
1.000 46.757 1000000 100 100 16 50 no
0.00 Infinity 0 0.00 0.000 0.000
HNSW
1.000 52.029 1000000 100 250 16 50 no
0.00 Infinity 0 0.00 0.000 0.000
HNSW
```
With this fix:
```
recall latency(ms) nDoc topK fanout maxConn beamWidth quantized
visited selectivity filterType vec_disk(MB) vec_RAM(MB) indexType
0.734 9.018 1000000 100 50 16 50 no
8951 0.05 pre-filter 0.000 0.000 HNSW
0.742 10.259 1000000 100 100 16 50 no
9857 0.05 pre-filter 0.000 0.000 HNSW
0.771 10.981 1000000 100 250 16 50 no
12117 0.05 pre-filter 0.000 0.000 HNSW
```
