Attribute operators

$not

Negates the nested condition(s).

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $not: {
        $contains: 'Hello World',
      },
    },
  },
});

$eq

Attribute equals input value.

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $eq: 'Hello World',
    },
  },
});

$eq can be omitted:

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: 'Hello World',
  },
});

$eqi

Attribute equals input value (case-insensitive).

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $eqi: 'HELLO World',
    },
  },
});

$ne

Attribute does not equal input value.

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $ne: 'ABCD',
    },
  },
});

$nei

Attribute does not equal input value (case-insensitive).

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $nei: 'abcd',
    },
  },
});

$in

Attribute is contained in the input list.

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $in: ['Hello', 'Hola', 'Bonjour'],
    },
  },
});

$in can be omitted when passing an array of values:

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: ['Hello', 'Hola', 'Bonjour'],
  },
});

$notIn

Attribute is not contained in the input list.

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $notIn: ['Hello', 'Hola', 'Bonjour'],
    },
  },
});

$lt

Attribute is less than the input value.

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    rating: {
      $lt: 10,
    },
  },
});

$lte

Attribute is less than or equal to the input value.

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    rating: {
      $lte: 10,
    },
  },
});

$gt

Attribute is greater than the input value.

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    rating: {
      $gt: 5,
    },
  },
});

$gte

Attribute is greater than or equal to the input value.

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    rating: {
      $gte: 5,
    },
  },
});

$between

Attribute is between the 2 input values, boundaries included (e.g., $between[1, 3] will also return 1 and 3).

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    rating: {
      $between: [1, 20],
    },
  },
});

$contains

Attribute contains the input value (case-sensitive).

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $contains: 'Hello',
    },
  },
});

$notContains

Attribute does not contain the input value (case-sensitive).

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $notContains: 'Hello',
    },
  },
});

$containsi

Attribute contains the input value. $containsi is not case-sensitive, while $contains is.

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $containsi: 'hello',
    },
  },
});

$notContainsi

Attribute does not contain the input value. $notContainsi is not case-sensitive, while $notContains is.

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $notContainsi: 'hello',
    },
  },
});

$startsWith

Attribute starts with input value (case-sensitive).

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $startsWith: 'ABCD',
    },
  },
});

$startsWithi

Attribute starts with input value (case-insensitive).

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $startsWithi: 'ABCD', // will return the same as filtering with 'abcd'
    },
  },
});

$endsWith

Attribute ends with input value (case-sensitive).

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $endsWith: 'ABCD',
    },
  },
});

$endsWithi

Attribute ends with input value (case-insensitive).

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $endsWith: 'ABCD', // will return the same as filtering with 'abcd'
    },
    },
  },
});

$null

Attribute is null.

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $null: true,
    },
  },
});

$notNull

Attribute is not null.

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: {
      $notNull: true,
    },
  },
});

Logical operators

$and

All nested conditions must be true.

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    $and: [
      {
        title: 'Hello World',
      },
      {
        createdAt: { $gt: '2021-11-17T14:28:25.843Z' },
      },
    ],
  },
});

$and will be used implicitly when passing an object with nested conditions:

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    title: 'Hello World',
    createdAt: { $gt: '2021-11-17T14:28:25.843Z' },
  },
});

$or

One or many nested conditions must be true.

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    $or: [
      {
        title: 'Hello World',
      },
      {
        createdAt: { $gt: '2021-11-17T14:28:25.843Z' },
      },
    ],
  },
});

$not

Negates the nested conditions.

Example

const entries = await strapi.documents('api::article.article').findMany({
  filters: {
    $not: {
      title: 'Hello World',
    },
  },
});

✏️ Note

$not can be used as:

• a logical operator (e.g. in filters: { $not: { // conditions… }})
• an attribute operator (e.g. in filters: { attribute-name: $not: { … } }).

💡 Tip

$and, $or and $not operators are nestable inside of another $and, $or or $not operator.
