facetIntervals property

If you don't set the facet SearchRequest.FacetSpec.FacetKey.intervals in the request to a numerical attribute, then we use the computed intervals with rounded bounds obtained from all its product numerical attribute values.

The computed intervals might not be ideal for some attributes. Therefore, we give you the option to overwrite them with the facet_intervals field. The maximum of facet intervals per CatalogAttribute is 40. Each interval must have a lower bound or an upper bound. If both bounds are provided, then the lower bound must be smaller or equal than the upper bound.
