Class DirectoryTaxonomyReader
A TaxonomyReader which retrieves stored taxonomy information from a Lucene.Net.Facet.Taxonomy.Directory.DirectoryTaxonomyReader.Directory.
Reading from the on-disk index on every method call is too slow, so this implementation employs caching: Some methods cache recent requests and their results, while other methods prefetch all the data into memory and then provide answers directly from in-memory tables. See the documentation of individual methods for comments on their performance.
