VIVA Learning own content from subsites

Hello

I like to know if I can use on the SharePoint Site Collection (Landig Page) for own content subsites.

We have created a structure based on the BA & BU's of the company and utilizing for BU's subsites in VIVA Learning. The question is now, will be the content on the subsites (libraries) indexed?

Or can I use only folders in that site collection?

STRUCTURE

                                                               BA

                            BU-A                          BU-B                        BU-C

                            Library-Finance          Library-Finance       Library-Finance

                            Library-HRD

The idea is to give each BU the possibility to manage their own content and on BA level the content for ALL globally.

The index for the own content in the SharePoint Site will be created in 24h from the Mirosoft cloud.

I like to know if the subsites in that site will be indexed too...

Any help is appreciated and thanks in advance.

Kind regards

Michael
