# Class RandomFacetSource

java.lang.Object
org.apache.lucene.benchmark.byTask.feeds.ContentItemsSource
org.apache.lucene.benchmark.byTask.feeds.FacetSource
org.apache.lucene.benchmark.byTask.feeds.RandomFacetSource

All Implemented Interfaces:
  `Closeable`, `AutoCloseable`

public class RandomFacetSource extends FacetSource
Simple implementation of a random facet source

Supports the following parameters:

- rand.seed - defines the seed to initialize `Random` with (default: 13).
- max.doc.facet.dims - Max number of random dimensions to create (default: 5); actual number of dimensions would be anything between 1 and that number.
- max.doc.facets - maximal #facets per doc (default: 10). Actual number of facets in a certain doc would be anything between 1 and that number.
- max.facet.depth - maximal #components in a facet (default: 3). Actual number of components in a certain facet would be anything between 1 and that number.
