body:

The query class is used to filter queries to the database.  It's available
through either the [Pad :ref](../pad/) or through things like the
[children :ref](../record/children/) property of records.

Most operations on a query object return another one which will return a
more filtered result.

## Example

Here a basic example of how to filter something in a template:

```html+jinja
<ul>
{% for item in this.children.filter(F.status == 'published') %}
  <li>{{ item.title }}</li>
{% endfor %}
</ul>
```
