: 'score' is a pseudo-field, i.e., it does not actually exist in
: the index, which is probably why it cannot be faceted on.
: Faceting on a rounded score seems like an unusual use
: case. What requirement are you trying to address?
agreed, more details would be helpful.
FWIW: the only way available to facet on functions is to use facet.query
along with the {!frange} paser to create facet constraints based on ranges
of function values that you specify.
there is no othe way i can think of to facet over function values -- there
is an open issue where people were discussing it, but i don't think there
wa ever a functional patch...
