Redis as a document database quick start guide
Understand how to use Redis as a document database
This quick start guide shows you how to:
- Create a secondary index
- Add JSON documents
- Search and query your data
The examples in this article refer to a simple bicycle inventory that contains JSON documents with the following structure:
{
"brand": "brand name",
"condition": "new | used | refurbished",
"description": "description",
"model": "model",
"price": 0
}
Setup
The easiest way to get started with Redis Stack is to use Redis Cloud:
-
Create a free account.
-
Follow the instructions to create a free database.
This free Redis Cloud database comes out of the box with all the Redis Stack features.
You can alternatively use the installation guides to install Redis Stack on your local machine.
Connect
The first step is to connect to your Redis Stack database. You can find further details about the connection options in this documentation site's connection section. The following example shows how to connect to a Redis Stack server that runs on localhost (-h 127.0.0.1) and listens on the default port (-p 6379):
> redis-cli -h 127.0.0.1 -p 6379Are you tired of using redis-cli? Try Redis Insight - the developer GUI for Redis.

}Tip:
You can copy and paste the connection details from the Redis Cloud database configuration page. Here is an example connection string of a Cloud database that is hosted in the AWS region us-east-1 and listens on port 16379: redis-16379.c283.us-east-1-4.ec2.cloud.redislabs.com:16379. The connection string has the format host:port. You must also copy and paste your Cloud database's username and password and then pass the credentials to your client or use the AUTH command after the connection is established.Create an index
As explained in the in-memory data store quick start guide, Redis allows you to access an item directly via its key. You also learned how to scan the keyspace. Whereby you can use other data structures (e.g., hashes and sorted sets) as secondary indexes, your application would need to maintain those indexes manually. Redis Stack turns Redis into a document database by allowing you to declare which fields are auto-indexed. Redis Stack currently supports secondary index creation on the hashes and JSON documents.
The following example shows an FT.CREATE command that creates an index with some text fields, a numeric field (price), and a tag field (condition). The text fields have a weight of 1.0, meaning they have the same relevancy in the context of full-text searches. The field names follow the JSONPath notion. Each such index field maps to a property within the JSON document.
> FT.CREATE idx:bicycle ON JSON PREFIX 1 bicycle: SCORE 1.0 SCHEMA $.brand AS brand TEXT WEIGHT 1.0 $.model AS model TEXT WEIGHT 1.0 $.description AS description TEXT WEIGHT 1.0 $.price AS price NUMERIC $.condition AS condition TAG SEPARATOR ,
