Method Detail

createFacetsAggregator

public FacetsAggregator createFacetsAggregator(FacetIndexingParams fip)

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.
