In this module, you will:
- Use the Cypher QA (question-answering) chain to query the graph using natural language queries.
- Create a custom Cypher generation prompt include specific instructions and examples queries.
- Explore how restricting the schema can support more focused queries.
- Add a text to Cypher retriever to a LangChain agent.
