In the user interface, you can narrow displayed data using grid column filters, or filters displayed in the sidebar. To enable that, apply #[Filter\*]
attributes to class properties.
Applied filters appear in the URL query parameters, for example, .../edit?id=5+16+19
, and on the page.
You can apply filters not only to a grid page, but also to a form page - to mass edit all matching objects, or to an action URL (edit, delete, or custom) - to perform the action on all matching objects.
In the same way, you can apply filters to the API URLs in order to retrieve or modify matching objects in a script.
