title: Index
---

An index is the basic container for organizing your data. Besides managed indexes using [LlamaCloud](/docs/llamaindex/modules/data/data_index/managed), LlamaIndex.TS supports three indexes:


- `VectorStoreIndex` - will send the top-k `Node`s 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 `Node`s to the LLM

```typescript
import { Document, VectorStoreIndex } from "llamaindex";

const document = new Document({ text: "test" });

const index = await VectorStoreIndex.fromDocuments([document]);
```
