如何使用Elasticsearch创建动态价格范围过滤器

Question

price range aggregations

{
  "aggs": {
    "price_ranges": {
      "range": {
        "field": "price",
        "ranges": [
          {
            "to": 50
          },
          {
            "from": 50,
            "to": 100
          },
          {
            "from": 100
          }
        ]
      }
    },
    "price_stats": {
      "extended_stats": {
        "field": "price"
      }
    }
  }
}

Is there a way I can make the ranges dynamic. for example, min_price in place of 50 and max_price in place of 100. Or use something like "price_stats.max" for max_price?

Answer 1

You can get something like this

"max_price" : { "max" : { "field" : "discountprice" } },
"min_price" : { "min" : { "field" : "discountprice" } } 

then create a range in application layer
