Document Selector

The Document Selector is a function common to the query tool and several analysis tools. It allows you to select which documents your query or analysis applies to.

Default state

By default, the Document Selector is collapsed and targets all documents in your project.

Inputs

You can select which documents your query or analysis applies to by:

• Documents
• Tags
• Document types (video, audio, image, document, survey)
• Folder

TIP

You cannot simply drag documents directly from the Document Browser onto the Document Selector canvas. Instead, they must be dropped into a pre-existing Document node box on the canvas.

Operators

You can add logical operators into your document selection to refine it. Magnolia uses these logical operators:

Operator	Output
Union	Selects documents from Input 1 and Input 2
Intersect	Selects documents where both Input 1 and Input 2 are met
Subtract	Selects documents where Input 1 is met but Input 2 is not met

TIP

You can use the output of any logical operator as the input to another logical operator.

Selected documents list

For convenience, the Document Selector shows you which documents your selection targets.

TIP

Remember to connect your selection to the Result node box.
