Azure AI-102

AI Search + RAG on Azure

8 min+80 XPStep 1/11

Four moving pieces

Azure AI Search pipelines flow: data source (Blob, ADLS, SQL, Cosmos DB) → indexer (crawls on a schedule, detects changes) → optional skillset (AI enrichment: OCR, entity recognition, key phrases, custom skills) → index (fields marked searchable / filterable / sortable / facetable, plus vector fields).

Queries hit the index — never the raw documents.

analogy

Think library: the indexer is the librarian shelving books, the skillset is the translator/annotator, the index is the card catalog you actually search.
