org.apache.lucene.facet.sampling.TakmiSampleFixer
Fix sampling results by correct results, by counting the intersection between two lists: a TermDocs (list of documents in a certain category) and a DocIdSetIterator (list of documents matching the query).
This fixer is suitable for scenarios which prioritize accuracy over performance.
Note: for statistically more accurate top-k selection, set {@link SamplingParams#setOversampleFactor(double) oversampleFactor} to atleast 2, so that the top-k categories would have better chance of showing up in the sampled top-cK results (see {@link SamplingParams#getOversampleFactor} @lucene.experimental

    sampleParams.setMaxSampleSize(100);
    sampleParams.setMinSampleSize(100);
    sampleParams.setSamplingThreshold(100);
    sampleParams.setOversampleFactor(1.0d);
    if (random().nextBoolean()) {
      sampleParams.setSampleFixer(new TakmiSampleFixer(indexReader, taxoReader, fsp));
    }
    final Sampler sampler = new RandomSampler(sampleParams, random());
