How can I exclude the price filter from the calculation of the price_ranges facet? In other words, the price_ranges facet should take into account all of the filters except for price.

Exclude filter from facet

{
  query : {
    "filtered" : {
      "query" : {
        "match_all" : {}
      },
      "filter" : {
        "and" : [
          {
            "term" : {
              "colour" : "Red"
            }
          },
          {
            "term" : {
              "feature" : "Square"
            }
          },
          {
            "term" : {
              "feature" : "Shiny"
            }
          },
          {
            "range" : {
              "price" : { 
                "from" : "10",
                "to" : "20"
              }
            }
          }
        ]
      }
    }
  },
  "facets" : {
    "colours" : {
      "terms" : {
        "field" : "colour"
      }
    },
    "features" : {
      "terms" : {
        "field" : "feature"
      }
    },
    "price_ranges" : {
      "statistical" : {
        "field" : "price"
      }
    }
  }
}
