Search query issue

Hi Everyone,
My problem is about filter and get terms.
İ wanna get term counts like zalando.de 1
When i clicked any color other colors not seeing after refresh.
I could not found any example for nested products and filters.

// My index
PUT products
{
  "mappings": {
    "product": {
      "properties": {
        "name": { "type": "text" },
        "permalink": { "type": "text" },
        "images": {"type" : "text"},
        "variations": {
          "type": "nested",
          "properties": {
            "size": { "type": "keyword" },
            "color": { "type": "keyword" },
            "brand": { "type": "keyword" },
            "brand-slug": { "type": "keyword" },
            "price": {"type": "double" },
            "sale_price": {"type": "double" },
            "stock": {"type": "integer" }
          }
        },
        "categories": {
          "type": "nested",
          "properties": {
            "id": { "type": "integer" },
            "name": { "type": "keyword" },
            "slug": { "type": "keyword" }
          }
        }
      }
    }
  }
}
