About
Azure AI Search, also referred to as Foundry IQ, is an enterprise search and retrieval service for retrieval-augmented generation (RAG) applications. It supports keyword search, vector search, and hybrid search in a single service, and includes knowledge sources and knowledge bases for connecting data from SharePoint, Azure Blob Storage, Microsoft OneLake, Fabric IQ, Work IQ, MCP, and the web.
The service includes built-in indexers for Azure Cosmos DB, Azure SQL Database, Azure Blob Storage, and Microsoft SQL Server on Azure Virtual Machines, plus import and transformation tooling in the Azure portal for parsing, chunking, enrichment, and embedding. The pricing page states that Azure free for up to 30 days is available through an Azure account, while the product itself is billed through Foundry IQ pricing for serverless agent workloads.

Free Tier Value
This page does not show any concrete free tier, credit, or trial for Azure AI Search, so there is no defensible monthly free-tier value to estimate. The pricing link points to a separate pricing page, but with no extracted free-tier bullets or published allowance here, the offer should be treated as having no measurable free tier on this page. A credit card requirement is not stated either way.
What's included in the free tier
- Free tier: 50 MB of storage per service, shared infrastructure.
- Up to 3 indexes on the Free tier.
- No hourly search-unit charge on the Free tier.
See Azure AI Search pricing for current limits.
