Examples of FacetIndexingParams

org.apache.lucene.facet.index.params.FacetIndexingParams

Parameters on how facets are to be written to the index. For example, which fields and terms are used to refer to the indexed posting list.

If non-default parameters were used during indexing, the same parameters must also be passed during faceted search. This requirement is analogous to the requirement during search to know which fields were indexed, and which Analyzer was used on the text. @lucene.experimental

org.apache.lucene.facet.params.FacetIndexingParams

Defines parameters that are needed for facets indexing. Note that this class does not have any setters. That's because overriding the default parameters is considered expert. If you wish to override them, simply extend this class and override the relevant getter.

NOTE: This class is also used during faceted search in order to e.g. know which field holds the drill-down terms or the fulltree posting. Therefore this class should be initialized once and you should refrain from changing it. Also note that if you make any changes to it (e.g. suddenly deciding that drill-down terms should be read from a different field) and use it on an existing index, things may not work as expected. @lucene.experimental

    boolean useRandomSampler = random().nextBoolean();
    for (int partitionSize : partitionSizes) {
      try {
        // complements return counts for all ordinals, so force ALL_PARENTS indexing
        // so that it's easier to compare
        FacetIndexingParams fip = getFacetIndexingParams(partitionSize, true);
        initIndex(fip);
        // Get all of the documents and run the query, then do different
        // facet counts and compare to control
        Query q = new TermQuery(new Term(CONTENT_FIELD, BETA)); // 90% of the docs
