### Description Link to [Jira](https://issues.apache.org/jira/browse/LUCENE-10559) ### Solution Added a `prefilter` and `filterSelectivity` argument to KnnGraphTester to be able to compare pre and post-filtering benchmarks `filterSelectivity` expresses the selectivity of a filter as proportion of passing docs that are randomly selected. We store these in a FixedBitSet and use this to calculate true KNN as well as in HNSW search In case of post-filter, we over-select results as `topK / filterSelectivity` to get final hits close to actual requested `topK` For pre-filter, we wrap the FixedBitSet in a query and pass it as prefilter argument to KnnVectorQuery -- This is an automated message from the Apache Git Service.
