Create an Index: Use
1VectorStoreIndex
to build an index from these documents for efficient querying.
Set Up Query Engine: Transform your index into a querying machine with
1index.as_query_engine()
.
Query the Data: Finally, ask your index questions—& it will respond within seconds!

Example: Setting Up Your First Application

Here's what this looks like in code:
```python from llama_index.core import VectorStoreIndex, SimpleDirectoryReader

documents = SimpleDirectoryReader("data").load_data() index = VectorStoreIndex.from_documents(documents) query_engine = index.as_query_engine() response = query_engine.query("What is the author’s background?") print(response) ``` With this setup, you can start querying your data repository instantly!
