ioredis - Upstash Documentation

If you're already using ioredis in your project, you can use Redis Search without switching to the @upstash/redis client. The @upstash/search-ioredis package wraps your existing ioredis instance and exposes the full Redis Search API.

Installation

npm install @upstash/search-ioredis ioredis

Setup

import IORedis from "ioredis";import { createSearch, s } from "@upstash/search-ioredis";// Create ioredis client using your Upstash Redis URLconst ioredis = new IORedis(process.env.REDIS_URL);// Create search clientconst search = createSearch(ioredis);

The REDIS_URL should be your Upstash Redis connection string in the format:

rediss://default:<PASSWORD>@<YOUR-DATABASE>.upstash.io:6379

Create an Index

const schema = s.object({  name: s.string(),  description: s.string(),  category: s.string().noTokenize(),  price: s.number(),  inStock: s.boolean(),});await search.createIndex({  name: "products",  dataType: "json",  prefix: "product:",  schema,});

Get an Index Client

Use search.index() to get a client for an existing index without making a Redis call:

const index = search.index({ name: "products", schema });

Add Data

Add data using standard Redis commands via your ioredis client. Any key matching the index prefix is automatically indexed:

await ioredis.call("JSON.SET", "product:1", "$", JSON.stringify({  name: "Wireless Headphones",  description: "Premium noise-cancelling wireless headphones with 30-hour battery life",  category: "electronics",  price: 199.99,  inStock: true,}));

Search Data

// Query with a filterconst results = await index.query({  filter: { description: "wireless" },});// Count matching documentsconst count = await index.count({  filter: { price: { $lt: 150 } },});

Wait for Indexing

Index updates are batched for performance. Use waitIndexing() when you need queries to reflect recent writes:

await index.waitIndexing();

Describe an Index

const description = await index.describe();

Drop an Index

const result = await index.drop();// Returns 1 (dropped) or 0 (index not found)

The adapter exposes the exact same search API as @upstash/redis. Refer to the Index Management, Querying, Aggregations, and Schema Definition pages for the full API reference.
