- Description copied from class:
FacetRequest
- Returns the
FacetsAggregator
which can aggregate the categories of
this facet request. The aggregator is expected to aggregate category values
into FacetArrays
. If the facet request does not support that, e.g.
RangeFacetRequest
, it can return null
. Note though that
such requests require a dedicated FacetsAccumulator
.
