Ollama

To use Ollama embeddings, you need to import OllamaEmbedding from llamaindex.

Note that you need to pull the embedding model first before using it.

In the example below, we're using the nomic-embed-text model, so you have to call:

ollama pull nomic-embed-text
import { OllamaEmbedding, Settings } from "llamaindex";

Settings.embedModel = new OllamaEmbedding({ model: "nomic-embed-text" });

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,
});
