In this video, I explain how semantic search works in a Retrieval-Augmented Generation (RAG) system using LangChain.
We first understand semantic search with simple real-life examples and vector intuition.
Then, we move to a hands-on demo using a PDF file and LangChain.
This video covers:
What is semantic search?
Why keyword search is not enough
How embeddings represent meaning
Loading a PDF in LangChain
Chunking documents
Creating embeddings
Storing data in a vector store
Retrieving top-K relevant chunks using similarity search
This is beginner-friendly and perfect for:
RAG learners
LangChain beginners
AI/ML interview preparation
