Hi, my first time posting here. I’m building a RAG application that takes in blog posts as a knowledge base and guide readers to the appropriate blog post based on their interest. However, I'm having a trouble grabbing the links to the relevant articles when relying to the user I’m using - Pinecone as a vector store - Langchain agent with gpt-3.5-turbo I have embedded the blog posts and put URLs as a metadata. Does anybody know how to grab the links associated with the articles?
