Section titled “Load and index documents”For this example, we will use a single document. In a real-world scenario, you would have multiple documents to index.
import { Document, VectorStoreIndex } from "llamaindex";
const document = new Document({ text: essay, id_: "essay" });
const index = await VectorStoreIndex.fromDocuments([document]);const queryEngine = index.asQueryEngine();
const query = "What is the meaning of life?";
const results = await queryEngine.query({ query,});Full Example
