import { DataberryRetriever } from "langchain/retrievers/databerry";



const retriever = new DataberryRetriever({

  datastoreUrl: "https://api.databerry.ai/query/clg1xg2h80000l708dymr0fxc",

  apiKey: "DATABERRY_API_KEY", // optional: needed for private datastores

  topK: 8, // optional: default value is 3

});



// Create a chain that uses the OpenAI LLM and Databerry retriever.

const chain = RetrievalQAChain.fromLLM(model, retriever);



// Call the chain with a query.

const res = await chain.call({

  query: "What's Databerry?",

});



console.log({ res });

/*

{

  res: {

    text: 'Databerry provides a user-friendly solution to quickly setup a semantic search system over your personal data without any technical knowledge.'
