Hi all.
Is it possible to have "type wide" term facets with [all_terms: true] ?
I have 2 types in the same index but when I request a terms facet with
all_terms=true, it returns the terms in the 2 types.
I already tried with a facet filter (see the exemple below) but it was the
same.
{
"query" : {
"match_all" : { }
},
"size":0,
"facets" : {
"ENGINE_FACET" : {
"terms" : {
"field" : "engine",
"size" : 10,
"order" : "term",
"all_terms" : true
},
"facet_filter" : {
"type" : {
"value" : "vehicle1"
}
}
}
}
}
Regards,

Hi Mehrez,
The all_terms setting indicate whether you want to terms which have had 0
count in the result to be filtered out (all_terms=false) or returned as
well (all_terms=true). Since facets always work with all the terms in the
index, you will may always get terms that belong to all types if you use
all_terms=true. The facet filter works by limiting the documents that are
considered for this facet so all terms of non-vehicle1 types remain on
count 0 but are still returned.
If you want complete separation between types, you might considering using
an index per vehicle type. You can still search all them using an alias if
you need to, or search only one & facet with all_terms=true and get what
you want.
Cheers,
Boaz

Thanks Boaz for your clarification.
I fixed it by indexing the property under a different name in each type
