Index

An index is the basic container for organizing your data. Besides managed indexes using LlamaCloud, LlamaIndex.TS supports three indexes:

• VectorStoreIndex - will send the top-k Nodes to the LLM when generating a response. The default top-k is 2.
• SummaryIndex - will send every Node in the index to the LLM in order to generate a response
• KeywordTableIndex extracts and provides keywords from Nodes to the LLM

import { Document, VectorStoreIndex } from "llamaindex";
 
const document = new Document({ text: "test" });
 
const index = await VectorStoreIndex.fromDocuments([document]);
