**Redis** is a powerful in-memory data structure store that can be used for various use cases due to its speed, simplicity, and versatility. In this tutorial, we'll explore several common use cases: matchmaking, location-based search, job queue, leaderboard, and session store.
**Redis** is a powerful in-memory data structure store that can be used for various use cases due to its speed, simplicity, and versatility. In this tutorial, we'll explore several common use cases: matchmaking, job queue, leaderboard, and session store.

If you haven't done so already, you can upload the sample data related to this tutorial by clicking the button below. You will also need support for [JSON](https://redis.io/docs/latest/develop/data-types/json/) and [Search & query](https://redis.io/docs/latest/develop/interact/search-and-query/) in your database to take advantage of this tutorial fully.

### Location-based search

Location-based search involves finding and retrieving data that is relevant to a specific geographic location. Redis can be used to power location-based search applications by storing and indexing geospatial data, such as latitude and longitude coordinates, and providing fast and efficient search capabilities

```redis:[run_confirmation=true] Add a restaurant
// Add a restaurant as JSON
JSON.SET sample_restaurant:341 $ '{
"name": "Zen Galushca",
"cuisine": "Japanese",
"location": "-98.1221,30.8232"
