How to find YAML documents by value from an array inside them?

[afuno]

There are documents in YAML format that have the following data inside:

title: Test
slug: test

# ...

bands:
  - slug: band-1
    active: true
  - slug: band-2
    active: true

# ...

Can you please tell me what condition should be written in where to get documents for slug with value band-2?

There is currently no such example in the documentation. The example for categories is different and doesn't fit.

The first version had this example:

const produits = await this.$content('produits').where({ 'categories.slug': { $contains: 'haut' } }).fetch()

const produits = await this.$content('produits').where({ 'categories.slug': { $contains: ['haut', 'femme'] } }).fetch()

This where variant doesn't work.
