You can restrict the indexed contents by their type with the following two properties:

feeder.content.type.includes=Content_
feeder.content.type.excludes=\
  EditorPreferences,Preferences,Dictionary,Query

Note

Configuration not mandatory: The default configuration includes all content types except EditorPreferences, Preferences, Dictionary and Query.

The property feeder.content.type.includes contains a comma-separated list of content types to be included. Contrary the property feeder.content.type.excludes contains a comma-separated list of content types to be excluded. With a specified type all subtypes are included and excluded, respectively. It is an error to specify the same content type in both properties. Rules for more specific types override rules for less specific types.

Caution

Note, that the Content Feeder does not update already processed contents after changing the content types to index. A configuration change only affects newly processed contents. You must reindex as described in Section 3.5, “Reindexing”, if you want to update all contents or contents of a certain type.
