In the help article Select which resources to download, it says the following regarding removing resources and reclaiming hard drive space from the index:

Is this still accurate for Logos 10? It seems to be removing the resource from the downloaded index and listing it as in cloud resources automatically now. Am I correct in this? When I run a search after removing a resource I already see the resource showing in Cloud resources instead of downloaded without having to run "Rebuild Index". I'm just trying to confirm how this works in Logos 10.
