Channel Filter: Show Only Word Documents

Goal: Channel with only Microsoft Office Word Documents.

Limitation

This channel filter example uses File Type Metadata from Schemas > Files > Document (path: /schemas/file-types/DocumentMetadata).

Picturepark Setup

Layer: DocumentMetadata (System Schema available)
- Fields: ApplicationName, indexed
Content Schema: DocumentMetadata

In order to have the File Metadata available in filters, you must index the fields. Therefore open Schemas > File Types > Document > ApplicationName and Edit the field. In Search Behavior enable "Enable in filters".

Channel Filter

{
	"kind": "AndFilter",
	"filters": [
		{
			"kind": "TermFilter",
			"field": "contentSchemaId",
			"term": "DocumentMetadata"
		},
		{
			"kind": "TermFilter",
			"field": "documentMetadata.applicationName",
			"term": "Microsoft Office Word"
		}
	]
}

We could only use the TermFilter on ApplicationName, but we want to make sure that we only see documents here.
