Redis Vector Store Example with LangChain Go
Hello there! 👋 Welcome to this exciting example that demonstrates how to use a Redis vector store with LangChain Go! Let's dive in and see what this cool code does! 🚀
What's This All About?
This example showcases how to:
- Set up a Redis vector store
- Add documents to the store
- Perform similarity searches
- Use a retrieval-based question-answering system
It's a fantastic way to learn about vector databases and how they can be used in AI applications!
The Magic Ingredients 🧙♂️
- Redis: Our trusty vector store
- Ollama: A local LLM server for embeddings and text generation
- LangChain Go: The glue that brings it all together!
What Happens in the Code?
-
Setting Up: We start by connecting to a Redis server and creating a new vector store index.
-
Adding Data: We add a bunch of documents about cities to our vector store. Each document contains the city name and some metadata like population and area.
-
Similarity Search: We perform a similarity search for "Tokyo" and get the 2 most similar results. This shows how vector stores can find related information quickly!
-
Question Answering: Here's where it gets really cool! We set up a retrieval QA chain that:
- Takes a question
- Searches the vector store for relevant information
- Passes that info to an LLM to generate an answer
-
Embeddings: We use the Ollama server to generate embeddings for our documents and queries. This is what makes the similarity search possible!
Why This is Awesome 🌟
- Fast Searches: Vector stores allow for lightning-fast similarity searches on large datasets.
- Flexible Data: You can store any kind of data with associated metadata.
- AI-Powered QA: By combining a vector store with an LLM, you can create powerful question-answering systems.
Ready to Try?
Make sure you have Redis running locally and an Ollama server set up with the "gemma:2b" model. Then run the code and watch the magic happen!
Happy coding, and have fun exploring the world of vector stores and AI! 🎉🤖
