# Azure AI Search Skill This skill provides expert guidance for Azure AI Search. Covers troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, integrations & coding patterns, and deployment. It combines local quick-reference content with remote documentation fetching capabilities. ## How to Use This Skill > **IMPORTANT for Agent**: Use the **Category Index** below to locate relevant sections. For categories with line ranges (e.g., `L35-L120`), use `read_file` with the specified lines. For categories with file links (e.g., `[security.md](security.md)`), use `read_file` on the linked reference file > **IMPORTANT for Agent**: If `metadata.generated_at` is more than 3 months old, suggest the user pull the latest version from the repository. If `mcp_microsoftdocs` tools are not available, suggest the user install it: [Installation Guide](https://github.com/MicrosoftDocs/mcp/blob/main/README.md) This skill requires **network access** to fetch documentation content: - **Preferred**: Use `mcp_microsoftdocs:microsoft_docs_fetch` with query string `from=learn-agent-skill`. Returns Markdown. - **Fallback**: Use `fetch_webpage` with query string `from=learn-agent-skill&accept=text/markdown`. Returns Markdown. ## Category Index | Category | Lines | Description | |----------|-------|-------------| | Troubleshooting | L37-L48 | Diagnosing and fixing Azure AI Search indexer/skillset errors,

Limits, quotas, and capacity planning for Azure AI Search: billing/free enrichment, indexer schedules/concurrency/runtime, service capacity limits, and vector index size/throughput constraints. | | Security | L100-L142 | Securing Azure AI Search: RBAC/Entra ID, keys, encryption, network isolation, indexer auth to data sources (SQL, Storage, SharePoint, Cosmos, Functions), and document-level/label-based access control. | | Configuration | L143-L235 | Configuring Azure AI Search: data sources, indexers, skillsets, analyzers, vectorization, semantic ranking, monitoring, and agentic retrieval/knowledge bases for RAG and answer synthesis. | | Integrations & Coding Patterns | L236-L311 | Patterns and code for integrating Azure AI Search: indexers, skills, vectorization, query syntax (Lucene/OData), semantic ranking, filters, pagination, and app/Power BI integrations. | | Deployment | L312-L319 | Deploying and moving Azure AI Search: ARM/Bicep/Terraform provisioning, cross-region migration, and deploying C# search apps to Azure Container Apps. | ### Troubleshooting | Topic | URL | |-------|-----| | Troubleshoot Azure AI Search indexer errors and warnings |
