  • Type: list<string>
  • Default: [](no custom ranking)
  • Scope: settings
Algolia’s tie-breaking algorithm applies the custom ranking attributes in the order they’re listed. Use asc(attribute) or desc(attribute) to specify the sort direction for each attribute. To learn more, see Custom ranking.

​
Usage

  • Attribute names are case-sensitive.
  • Records with missing or null values for a custom ranking attribute are considered equal and are placed at the end of the result list, regardless of sort order.
  • Boolean values are sorted alphabetically: false comes before true in ascending order, and true comes before false in descending order.

​
Modifiers

​
asc
Sort by increasing value of the attribute.
​
desc
Sort by decreasing value of the attribute.

​
Example

The following example ranks tied records by decreasing popularity. Records with equal popularity will be ranked by ascending price.
