Query Engine API: Filtering

The Query Engine API offers the ability to filter results found with its findMany() method.

Results are filtered with the where parameter that accepts logical operators and attribute operators. Every operator should be prefixed with $.

Logical operators

$and

All nested conditions must be true.

Example

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

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

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

$not

Negates the nested conditions.

Example

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

✏️ NOTE

$not can be used:

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

💡 TIP

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

Attribute Operators

✋ CAUTION

Using these operators may give different results depending on the database's implementation, as the comparison is handled by the database and not by Strapi.

$not

Negates nested condition(s).

Example

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

$eq

Attribute equals input value.

Example

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

$eq can be omitted:

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

$ne

Attribute does not equal input value.

Example

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

$in

Attribute is contained in the input list.

Example

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

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

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

$notIn

Attribute is not contained in the input list.

Example

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

$lt

Attribute is less than the input value.

Example

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

$lte

Attribute is less than or equal to the input value.

Example

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

$gt

Attribute is greater than the input value.

Example

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

$gte

Attribute is greater than or equal to the input value.

Example

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

$between

Attribute is between the 2 input values.

Example

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

$contains

Attribute contains the input value (case-sensitive).

Example

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

$notContains

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

Example

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

$containsi

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

Example

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

$notContainsi

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

Example

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

$startsWith

Attribute starts with input value.

Example

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

$endsWith

Attribute ends with input value.

Example

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

$null

Attribute is null.

Example

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

$notNull

Attribute is not null.

Example

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