This allows you to aggregate the contents of multiple Collections into the current collection.

This may be used for scenarios like:

• having a Site Home Page that shows an aggregate news feed from all other Collections/Sections of the site;
• having a news feed that includes news from several other sections of the site;
• allowing search in several collections simultaneously;

To make this feature work, you should add the IDs of the collections you would like to aggregate, separating them with commas (i.e.: 2,3,4,5).

If you want to aggregate ALL the collections of this system into a single one (might be useful for global homepages), then enter a single asterisk *.
