You can filter your search results by numeric value. For example, you can filter by price, rating, or any other numeric value.

Setup a numeric field

To filter by numeric value, you must first set up a numeric field.

Indexing the following document into Elasticsearch will create a long field called price:

{
  "price": 10
}

and your mapping will look like this:

{
  "mappings": {
    "properties": {
      "price": {
        "type": "long"
      }
    }
  }
}

Filter Attribute Configuration

Add a filter attribute to your index configuration. The filter attribute will be used to filter your search results by price.

 {
  "filter_attributes": [
    { attribute: 'price', field: 'price', type: 'numeric' },
  ]
 }

Alternatively, you could setup the attribute under facet_attributes to make it available for faceting.

 {
  "facet_attributes": [
    { attribute: 'price', field: 'price', type: 'numeric' }
  ]
 }
 

The attribute name must be unique in both filter_attributes and facet_attributes. If you want to use the same attribute for both filtering and faceting, add it to facet_attributes only.

Using Filter Attributes

You can use the filter attribute in your search query to filter your search results by date within configure.

Syntax Examples

 "price:10" # price is 10
 "price:[10 TO 20]" # price is between 10 and 20
 "price:[10 TO *]" # price is greater than 10
 "price:[* TO 20]" # price is less than 20
