Now, let's move on and see how to implement a prize range filter as seen in some e-commerce websites. Consider the following screenshot of an e-commerce site:

In the preceding screenshot, you can see a price range filter on the left-hand side tab. By clicking on or specifying the price ranges, the products that fall within that range would be displayed. This is nothing but a numeric range filter.

The implementation of a numeric range filter is almost similar to the date range filter in Elasticsearch. The following code snippet shows how to implement a numeric range filter. Here is the sample; assume that you have an age field that is numeric in nature:

{
    "filtered" : {
        "filter" : {
            "range" : {
                "age" : {
                    "gte": 10,
                    "lte": 20
                }
            }
        }
    }
}

After reading the implementation of filters, which is to be followed, you would understand the snippet completely...
