+This indexing stage can be executed offline and only runs once to precompute the indexes for the dataset 
+so that each piece of content can be retrieved later. Since this is a small example, we will store and search the 
+embeddings locally. If you have a larger dataset, consider using a vector search engine like Pinecone, 
+Weaviate or Qdrant to power the search.
