Facet & Analytics Module

The new Facet & Analytics Module is a rewrite of Solr's previous faceting capabilities, with the following goals:

  • First class native JSON API to control faceting and analytics
  • First class integrated analytics support
  • Nest any facet type under any other facet type (such as range facet, field facet, query facet)
  • Ability to sort facet buckets by any calculated metric
  • Easier programmatic construction of complex nested facet commands
  • The structured nature of nested sub-facets are more naturally expressed in a nested structure like JSON rather than the flat structure that normal query parameters provide.
  • Support a much more canonical response format that is easier for clients to parse
  • Support a cleaner way to implement distributed faceting
  • Support better integration with other search features
  • Full integration with the JSON Request API
