+# Sample Questions
+
+By default, agents use OpenAI's file search capability with the documents in the `src/files` folder. To enable Azure AI Search instead, set the environment variable before the first time of provision and deployment:
+
+```shell
+azd env set USE_AZURE_AI_SEARCH_SERVICE true
+```
+
+When Azure AI Search is enabled, the system uses pre-computed embeddings from `src/data/embeddings.csv` rather than processing the individual files in the `src/files` folder.
