Alongside its free plan, Azure Search offers several SMB and enterprise pricing for all users to choose from. The plans are using pricing method wherein you only need to pay for the number of search units you used or provisioned for a given hour. Search units are the Azure Search resources used for your service. In addition, the pricing of the plans varies depending on the number of replicas and partitions you can use for scaling, the storage capacity you need for the partitions, the number of indices you can set up per service, and the region you belong.
The search units which you can use can also be combined to process more search queries per second, increase the number documents you can upload and manage, speed up data ingestion, and improve search performance. Moreover, you will be charged with a corresponding bandwidth cost when you transmit data in and out of Azure data centers.
