Azure AI Search Azure AI Search

Search-as-a-service for web and mobile app development

Pricing details

Offered in combinable units that include reliable storage and throughput, Azure AI Search allows developers to set-up and scale a search experience quickly and cost-effectively. As the volume of data or throughput needs of an application change, Azure AI Search can scale out to meet these needs, and then scale back down to reduce costs. To get more performance, a customer can combine units to gain more queries per second, or a higher document count, or both. Units can also be combined to enable high availability or faster data ingestion.

High density (HD) mode is an optional setting available for standard S3. High density mode enables customers to pack in a higher number of indices per Azure AI Search service. This is ideal for customers building multi-tenant SaaS apps that have a large number of small tenants, trials, or free accounts and want to provide a powerful search experience at a low cost per index.

You can enrich a limited number of documents for free, or attach a billable Cognitive Services resource for larger and more frequent workloads. Built-in cognitive skill execution is charged at the Cognitive Services Pricing Page , at the same rate as if you had performed the task directly. Learn more about skill execution .
