Problem

Scenario

You're building a system where a language model needs to find relevant text from a document collection before answering a user query. You want to use embeddings and a vector database so semantically similar content can be retrieved even when the wording differs.

Question

How would you use embedding vector databases in an AI system?

What this tests

Embedding generation for text chunks and queries
Vector search and nearest-neighbor retrieval
How retrieval supports a RAG pipeline
Trade-offs versus keyword search or fine-tuned QA
