NWBC Search bar for help documents

Hi,

Is possible link the help center to a network share folder and then put this available for all the users in the NWBC search bar so in that way they are going to be able to search documents using the NWBC search bar that is presented in the following screen?

I just installed the TREX 7.1 and I actiavted the "Help Center" object connectors in the transaction "ESH_COCKPIT" but if I try to search any of my documents that are in the network share folder I don't see that are displayed yet in the drop down list presented in the NWBC search bar. Do I missing something or this is not possible?

Thanks!
Carlos
