# Querying a SDTF graph

## Introduction

Your token system can be more complex than it seems. You will often need to interact with your token graph to transform a specific set of design tokens within a Specify configuration.

This article will help you understand how you can query your token graph to select a specific set of tokens.

## Query structure

Every Query holds a single a `where` property being an object, to select one branch of the graph, or an array of objects, to select many branches of the graph (OR statement).

```typescript
Type Query = { where: Where | Array<Where> }
```

The `where` property splits in 3 kinds: token, group, collection - offering a dedicated set of options to match against the given kind.

The `name` property accepts a RegExp for a value. These resources will help you debug your regular expressions:

### Where Token

```typescript
type WhereToken = {
  token: 
    | string
    | {
      name?: string;
      description?: string?;
    }
  select: 
    | true
    | {
      token?: boolean;
      parents?:
        | true
        | {
          groups?: true;
          collections?: true;
        }
    }
}
```

### Where Group

```typescript
type WhereGroup = {
  group: string;
  select: 
    | true
    | {
      group?: boolean;
      parents?:
        | true
        | {
          groups?: true;
          collections?: true;
        }
      children:
        | true
        | {
          groups?: true;
          collections?: true;
          tokens?: true;
        }
    }
}
```

### Where Collection

```typescript
type WhereCollection = {
  collection: string;
  select: 
    | true
    | {
      collection?: boolean;
      parents?:
        | true
        | {
          groups?: true;
        }
      children:
        | true
        | {
          groups?: true;
          tokens?: true;
        }
    }
}
```
