  • Type: list<string>
  • Default: ["typo", "geo", "words", "filters", "proximity", "attribute", "exact", "custom"]
  • Scope: settings
This setting controls how Algolia sorts your results. The tie-breaking algorithm sequentially applies ranking criteria in the order specified.
You can change the order of the default criteria but you shouldn’t. The out-of-the-box ranking order works for most uses. Before changing this parameter, consider running an A/B test to ensure your changes will positively affect results.

​
Usage

  • Attribute names are case-sensitive.
  • Add asc(attribute) or desc(attribute) to the list to sort by attributes such as price or popularity.
  • You can reorder or remove criteria to fine-tune ranking, but the default order works well for most situations.
  • Ranking also depends on the order of attributes in searchableAttributes.

​
Ranking criteria

​
typo
Rank results by the fewest spelling mistakes.
​
geo
Rank results by increasing distance. This option only applies when performing a geographical search.
​
words
Rank results by the number of matching query words, starting with the most matches. Only applies when using optionalWords.
​
filters
Rank results by filter score. This option is essential when using optionalFilters.
​
proximity
Rank results by how close the query words are to each other in the record.
​
attribute
Rank results based on the order of attributes defined in searchableAttributes.
​
exact
For single-word queries, follows the behavior defined by the exactOnSingleWordQuery setting. For multi-word queries, ranks by number of exact word matches.
​
custom
Rank results based on the values of attributes listed in customRanking. If not included in ranking, the custom ranking criterion is ignored.

​
Modifiers

​
asc
Sort in ascending order (lowest to highest).
​
desc
Sort in descending order (highest to lowest).
