Hi All,
As per documentation of SortedSetDocValuesFacetCounts, Compute facets counts from previously indexed > > SortedSetDocValuesFacetField, without require a separate taxonomy index. > Faceting is a bit slower (~25%), and there is added cost on every > IndexReader open to create a new SortedSetDocValuesReaderState. > Furthermore, this > > does not support hierarchical facets; only flat (dimension + label) > facets, but it uses quite a bit less RAM to do so. > what is meant by " does not support hierarchical facets; only flat" here? what functionality we will miss because of this? other than faster faceting...Is there any benefit of using taxonomy index over docvalues field for faceting? -- Kumaran R
