## Uses of Class
org.apache.lucene.facet.taxonomy.TaxonomyReader

Packages that use TaxonomyReader
org.apache.lucene.facet.complements: Allows to cache the total counts of categories, so that during search which returns a large number of results (>60% of segment size), the complement set of matching documents is counted.
org.apache.lucene.facet.partitions: Category Partitions
org.apache.lucene.facet.sampling: Facets sampling.
org.apache.lucene.facet.search: Facets search code.
org.apache.lucene.facet.taxonomy: Taxonomy of Categories
org.apache.lucene.facet.taxonomy.directory: Taxonomy index implementation using on top of a Directory.
org.apache.lucene.facet.util: Various utilities for faceted search

Uses of TaxonomyReader in org.apache.lucene.facet.complements

Methods in org.apache.lucene.facet.complements with parameters of type TaxonomyReader
`TotalFacetCounts` `TotalFacetCountsCache.getTotalCounts(IndexReader indexReader, TaxonomyReader taxonomy, FacetIndexingParams facetIndexingParams)` Get the total facet counts for a reader/taxonomy pair and facet indexing parameters.
`void` `TotalFacetCountsCache.load(File inputFile, IndexReader indexReader, TaxonomyReader taxonomy, FacetIndexingParams facetIndexingParams)` Load `TotalFacetCounts` matching input parameters from the provided outputFile and add them into the cache for the provided indexReader, taxonomy, and facetIndexingParams.
