Creating and using nested attributes

Learn about nested attributes, and when to use them.

With nested attributes, you can add subcategories to your attributes. For example, instead of having a single attribute price, you might set up different prices as subcategories: price.net, price.gross, price.margin. Use ‘dot notation’ to separate the parent attribute from its child.

How to create nested attributes

You can create nested attributes by adding a JSON object to your records when you send them to Algolia. For example:

json

[
  {
    "country": "CA",
    "price": {
      "net": 2.3,
      "gross": 2.62
    }
  },
  {
    "country": "US",
    "price": {
      "net": 1.99,
      "gross": 1.75
    }
  }
]

An example of filtering nested attributes with an API client

js

const index = client.initIndex("your_index_name");

index
  .search("", {
    filters: "country:US AND price.gross < 2.0",
  })
  .then(({ hits }) => {
    console.log(hits);
  });

An example of filtering nested attributes with the Algolia CLI

sh

algolia search --indexName=your_index_name --filters='country:US AND price.gross < 2.0'

Where you can use nested attributes

You can use nested attributes wherever you might use a regular attribute, such as searchableAttributes and attributesForFaceting. Just make sure you use the appropriate dot notation such as price.country to refer to them.

There’s no limit on the number of nested attributes apart from the default restrictions on record size. The depth of nesting is also unlimited: you could use something like price.net.us.ca.
