What you'll learn
puzzle
Understand embeddings
Know what a vector encodes, what it does not, and which similarity measure to use.
layers
Chunk content well
Split documents so retrieved passages are self-contained and carry useful metadata.
gauge
Improve retrieval quality
Combine keyword and vector search, then rerank, and measure whether it helped.
shield
Ground every answer
Cite sources, and make the system say it does not know instead of inventing one.
