Yes, it is possible with Json facet api. Request (json facet part) looks like
this:
{code:language=java}
"facet" : {
"availabledates" : {
"field" : "departuredate",
"type" : "terms",
"limit" : 100,
"facet" : {
"card" : "hll(accommodationid)"
}
}
}
{code}
In the example, term facet is calculated for the date field (departuredate) and
then _hll_ function is used to get the number of unique values for
accommodationid field for each date bucket. And this is indeed equivalent of
grouped facet.
