    Description

      Hierarchical faceting with slow startup, low memory overhead and fast response. Distinguishing features as compared to SOLR-64 and SOLR-792 are

      • Multiple paths per document
      • Query-time analysis of the facet-field; no special requirements for indexing besides retaining separator characters in the terms used for faceting
      • Optional custom sorting of tag values
      • Recursive counting of references to tags at all levels of the output

      This is a shell around LUCENE-2369, making it work with the Solr API. The underlying principle is to reference terms by their ordinals and create an index wide documents to tags map, augmented with a compressed representation of hierarchical levels.
