Overview
These are notes on specifying the sort order in Drupal Facets.
Method
You can change the facet settings by accessing the following:
/admin/config/search/facets
Clicking the edit button for each facet navigates to the following screen:
At the bottom of the screen, there is a Facet sorting section where you can configure sorting by count and by name. To sort by name, uncheck Sort by count.
Summary
I hope this serves as a useful reference when working with Drupal.
