Faceting with nested Document

[Rajesh Kumar <ra...@gmail.com>]

Hi All,

I am trying to do faceting with "tag and exclude" on nested document
Below nested document sample
{"master_id":"8219",
        "color_label":["White"],
        "price":1550.0,
        "product_id":"8220",
        "size_label":["XS"],
        "color_option_id":["82"],
        "product":"PomPom Summer Dress",
        "child_sku":"VJ17MSCL02MAY-XS",
        "size_option_id":["94"],}

      {
        "title":"PomPom Summer Dress",
        "color_label":["White"],
        "price":1550.0,
        "product_id":"8219",
        "color_option_id":["82"],
        "product":"PomPom Summer Dress",
        "master_sku":"VJ17MSCL02MAY",
        "master_id":"0",}
My objective is to get count of products for the field like
color_label,size_label then filter query on these fields.Below is the query
which i m using to get products with size label "L" with faceting
query?q=title:pant&fq={!tag=label}size_label:L&fl=size_label,color_label,id,[child
parentFilter=master_id:0]&
json.facet={
size_label :
{type: terms,
field: size_label,
domain: { blockChildren:"master_id:0",excludeTags:label}
}
}

"response":{"numFound":0,"start":0,"docs":[]
  },
  "facets":{
    "count":0,
    "size_label":{
      "buckets":[{
          "val":"L",
          "count":39},
        {
          "val":"M",
          "count":39},
        {
          "val":"XS",
          "count":30},
        {
          "val":"XXL",
          "count":30}]}}}

here is no product in response (numFound=0) but still getting "facets"
node. Please help me to understand where i am doing wrong

The first two mistakes are:
 - using fq for children fields ,
 - using a value master_id:0 as a parents' filter
Regarding the question, you are getting non-zero facets because you exclude
filter produces empty results.
