Set up semantic ranking
Semantic ranking is automatically enabled for the Azure AI Search service at the service level and it is available for all indexes. Semantic ranking cannot be enabled or disabled on a per-index basis.
Configure semantic ranking
Before you configure semantic ranking, you must have an Azure AI Search service with at least one index.
Note
For semantic ranking, the AI Search service must have a billable tier. You cannot change the pricing tier of an AI Search service. If you need another pricing tier, you will have to re-create the service.
Semantic ranking is not available in every region. Before configuring semantic ranking, check that the region of your AI Search service supports semantic ranking. To see a list of regions that support semantic ranking, see Products available by region
