Azure AI Search

We used Azure AI Seach as a part of a RAG pipeline for an internal knowledge assistant, and overall it worked pretty well once everything was configured properly. The integration with the azure ecosystem is probably the biggest advantage. Since most of our infra was already on Azure, onboarding was easier compared to introducing another standalone vector database or search platform. That said, I wouldn't call the setup "simple". The first couple of weeks involved a lot of tuning, indexing experiments, schema changes, and figuring out why retrieval quality suddenly dropped after what looked like harmless updates. Once stabilized though, it became reliable enough for production use.
