Filtering

Most results that are paginated can also be filtered. This makes it easy to retrieve specific information, like any issues assigned to a particular user, but much more complex queries are also possible. For example, you could fetch all issues associated with a project that is supposed to be completed next week and have not yet been started.

For example, to return all urgent and high priority issues in the workspace, you can use the following query:

query HighPriorityIssues {
  issues(filter: { 
    priority: { lte: 2 }
  }) {
    nodes {
      id, title, priority
    }
  }
}

The above query will also return any issues that haven't been given any priority (their priority is 0). To exclude them, you can add another not equals comparator:

query HighPriorityIssues {
  issues(filter: { 
    priority: { lte: 2, neq: 0 }
  }) {
    nodes {
      id, title, priority
    }
  }
}

Comparators⁠

You can use the following comparators on string, numeric, and date fields:

Numeric and date fields additionally have the following comparators:

String fields additionally have the following comparators:

Optional values additionally support the null comparator, which can be used to return entities depending on whether the field has a value or not. The following query will return all issues that don't have a description:

query Issues {
  issues(filter: { 
    description: { null: true }
  }) {
    nodes {
      id, title, description
    }
  }
}

Logical operators⁠

By default, all fields described in the filter need to be matched. The filter merges all the conditions together using a logical and operator.

For example, The below example will find all urgent issues that are due in the year 2021.

query Issues {
  issues(filter: { 
    priority: { eq: 1 }
    dueDate: { lte: "2021" }
  }) {
    nodes {
      id, title, priority, dueDate
    }
  }
}

To change the logical operator, all filters support the or keyword that lets you switch to a logical or operator. For example, to filter for low-priority or un-prioritized issues that need to be completed in the year 2021, you can execute the following query:

query Issues {
  issues(filter: { 
    or: [
      { priority: { eq: 4 } },
      { priority: { eq: 0 } }
    ]
    dueDate: { lte: "2021" }
  }) {
    nodes {
      id, title, priority, dueDate
    }
  }
}

Filtering by relationship⁠

Data can also be filtered based on their relations. For example, you can filter issues based on the properties of their assignees. To query all issues assigned to a user with a particular email address, you can execute the following query:

query AssignedIssues {
  issues(filter: { 
    assignee: { email: { eq: "john@linear.app" } }
  }) {
    nodes {
      id
      title
      assignee {
        name
      }
    }
  }
}

Many-to-many relationships can be filtered similarly. The following query will find issues that have the Bug label associated.

query Issues {
  issues(filter: { 
    labels: { name: { eq: "Bug" } }
  }) {
    nodes {
      id, title
    }
  }
}

The above query returns all issues that have at least one label that matches the name Bug. To create a query where all labels on an issue are matched to the filter criteria, you can use the every keyword:

query Issues {
  issues(filter: { 
    labels: { every: { name: { eq: "Bug" } } }
  }) {
    nodes {
      id, title
    }
  }
}

The above would also filter out issues that have multiple labels, regardless of what they are.

Relative time⁠

All date fields support relative time, defined as ISO 8601 durations relative to the current date. This lets you create a filter that always returns all issues that are due in the next 2 weeks, regardless of when you run it:

query IssuesDue {
  issues(filter: { 
    dueDate: { lt: "P2W" }
  }) {
    nodes {
      id, title
    }
  }
}

Examples⁠

Find all bugs and defects from projects that are lead by any user named "John":

query Projects {
  projects(filter: { 
    lead: { name: { startsWith: "John" } } 
  }) {
    nodes {
      issues(filter: { 
        labels: { name: { in: ["Bug", "Defect"] } } 
      }) {
        nodes {
          id
          title
        }
      }
    }
  }
}

Find all issues assigned to me that have a comment containing a thumbs-up emoji:

query Issues {
  viewer {
    assignedIssues(filter: { 
      comments: { body: { contains: "👍" } } 
    }) {
      nodes {
        id
        title
      }
    }
  }
}

Find all issues that have been created by me and have been closed in the past two weeks:

query ClosedIssues {
  viewer {
    createdIssues(filter: { completedAt: { gt: "-P2W" } }) {
      nodes {
        id, title
      }
    }
  }
}

Find all started issues in ongoing projects that don't have an estimate:

query Issues {
  issues(
    filter: {
      estimate: { eq: 0 }
      state: { type: { eq: "started" } }
      project: { state: { eq: "started" } }
    }
  ) {
    nodes {
      title
      estimate
      project {
        name
      }
    }
  }
}
