Azure Cognitive Search allows developers to set up and scale a search experience quickly and cost-effectively. Consumption is offered in combinable search “units” that vary by storage and throughput, designed to meet customer needs and to scale up or down to optimise costs. Search units are billed hourly and are calculated as a function of index replicas and partitions (total number of units = partitions * replicas). This is not inclusive of enrichment costs. Please read this documentation first to understand how to calculate your billable search units.
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 Cognitive 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.
Storage Optimised editions offer significantly more storage at a reduced price per TB. These editions are ideal for solutions with a large volume of index data and low query demands throughout the day. This is well suited for internal applications searching over large file repositories, searching an archive of many years of business data or e-discovery.
You can enrich a limited number of documents for free or attach a billable Azure AI Applied Services resource for larger and more frequent workloads. Built-in cognitive skill execution is charged at the Azure AI Applied Services pay-as-you go price, at the same rate as if you had performed the task directly. Learn more about skill execution.

Semantic Search
With the new semantic search feature, you can use artificial intelligence to improve the relevance of your search results by finding documents that are semantically similar to the query terms. When you enable semantic search, you are charged a fixed monthly cost for the first 2,50,000 semantic queries and then an additional variable cost for any semantic queries beyond the first 2,50,000.
Semantic Search can be enabled only on Standard tiers (S1, S2, and S3) of Cognitive Search and has two pricing plans: a Free plan and a Standard plan.
| Free Plan | Standard Plan | |
|---|---|---|
| Semantic Search Pricing Plans | Up to 1,000 semantic queries per month |
0-2,50,000 semantic queries - $-/month1
$- per semantic query after the first 2,50,000 |
Cognitive Search: AI-Powered Content Augmentation
With the new Cognitive Search feature, you can use artificial intelligence to extract insights and structured information from your documents. Create pipelines that uses cognitive skills to enrich and bring structure to your data before it gets indexed. You can select from a variety of pre-built cognitive skills and also extend its power by creating your own custom skills. 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 pay-as-you go price, at the same rate as if you had performed the task directly. Learn more about skill execution.

Frequently asked questions
-
With Microsoft Azure Cognitive Search, you are billed on a flat, predictable hourly rate based on the number of units that have been used during any given hour.
-
You are billed the last search unit count detected within an hour. If you start with two units, then scale to four units, and then scale back down to two units all within an hour, you will likely be charged for two units.
-
The stop button is meant to stop traffic to your service instance. As a result, your service is still running and will continue to be charged the hourly rate.
-
You are billed the flat rate for each hour the unit exists, regardless of usage or if the unit is active for less than an hour. For example, if you create a unit and delete it five minutes later, your bill will reflect a charge for one unit hour.
-
Azure Cognitive Search units combine to provide additional throughput and storage. For example, to scale from 15 million documents to 30 million (additional partitions), a customer can purchase two units. To increase throughput (additional replicas), they can purchase two units. To increase both storage and throughput, a customer would need to purchase four units (2 replicas x 2 partitions = 4 search units).
-
Free is a free version of Azure Cognitive Search designed to provide developers a sandbox to test features and implementations of Azure Cognitive Search. It is not designed for production workloads. Basic, standard and storage optimised are the go-to options for building applications that benefit from a self-managed search-as-a-service solution. Standard delivers storage and predictable throughput that scales with application needs. Storage Optimised editions offer significantly more storage at a reduced price per TB. For very high-demand applications, please contact azuresearch_contact@microsoft.com.

Azure Cognitive Search is available in the new Microsoft Azure portal. First, you must sign up for an Azure subscription, then you can add an Azure Cognitive Search account to your Azure subscription via the gallery in the preview portal. Get more information.
