Examples of org.apache.lucene.facet.FacetsConfig

org.apache.lucene.facet.FacetsConfig
Records per-dimension configuration. By default a dimension is flat, single valued and does not require count for the dimension; use the setters in this class to change these settings for each dim.
NOTE: this configuration is not saved into the index, but it's vital, and up to the application to ensure, that at search time the provided {@code FacetsConfig} matches what was used during indexing. @lucene.experimental
