# Group By
A {doctitle} operation can be performed at [query](https://docs.coveo.com/en/231/) time by the Search API to retrieve the different available values for a certain [field](https://docs.coveo.com/en/200/) in the query result set, along with the number of occurrences of each of those values.

The [Coveo JavaScript Search Framework](https://docs.coveo.com/en/187/) performs Group By operations to generate [facets](https://docs.coveo.com/en/198/).
