Because I need the count and the result to return back to the client side. Both
the grouping and the facet offers me a solution to do that, but my doubt is
about performance ...
With Grouping my results are:
"grouped":{
"category":{
"matches": ...,
"groups":[{
"groupValue":"categoryXX",
"doclist":{"numFound":Important_number,"start":0,"docs":[
{
doc:id
category:XX
}
"groupValue":"categoryYY",
"doclist":{"numFound":Important_number,"start":0,"docs":[
{
doc: id
category:YY
}
And with faceting my results are :
"facet.prefix=whatever"
"facet_counts":{
"facet_queries":{},
"facet_fields":{
"namesXX":[
"whatever_name_in_category",76,
...
"namesYY":[
"whatever_name_in_category",76,
...
Both results are OK to me.

Asunto: Re: Grouping or Facet ?
Why not just use the first form of the document
and just facet.field=category? You'll get
two different facet counts for XX and YY
that way.
I don't think grouping is the way to go here.
