Tutorial: Building a LlamaIndex for Efficient Document Searching
Welcome to this step-by-step tutorial that will guide you through the process of creating a powerful document search engine using LlamaIndex. Let's get started!
Step 1: Import the Required Modules
from llama_index import VectorStoreIndex, SimpleDirectoryReader, download_loader # Download the PDFReader loader PDFReader = download_loader("PDFReader") # Create a SimpleDirectoryReader object loader = PDFReader()
Step 2: Load and Index Your Documents
# Load the PDF documents documents = loader.load_data(file=Path('amdpt.pdf')) # Create a VectorStoreIndex object index = VectorStoreIndex.from_documents(documents)
Step 3: Set Up the Query Engine
# Set the OpenAI API key os.environ["OPENAI_API_KEY"] = "" # Create a query engine object query_engine = index.as_query_engine()
Step 4: Search and Retrieve Information
# Query the index with your question question = "?" response = query_engine.query(question) # Print the response print(response)
