-We want our assistant to answer detailed questions based on the official park brochures (PDFs) located in `gs://ghacks-disneyland-on-gcp/disneyland_brochures/`.
+For a more streamlined pipeline, let's create chunks of the PDFs, then generate embeddings. Finally, use Vector search to find similarities:
 
-1. Create an **Object Table** pointing to the brochures bucket.
-2. Create a **Python UDF** in BigQuery to extract text and chunk the PDF files. You can use `pypdf` inside the UDF environment.
-3. Chunk the PDFs, and generate embeddings for each text chunk using a remote BQML embedding model (`gemini-embedding-001`).
-4. Store the chunks and their vector embeddings in a table `brochure_embeddings`.
