Aggregations in Search Results
For further aggregating the results, the Search API provides the aggregations type. This type allows fetching price information, product variant attribute information, and more in the result set.
In order to perform these operations, ensure that you have the proper authentication (if necessary) and user permissions.
You can also count the number of items satisfying a particular criterion by using the count field. The query below retrieves all the products as well as the variants belonging to the search term 'sofa'. Then we use the aggregations type to get the topic names and the amount of variants belonging to each of the topics returned.
