SharePoint 2013 - Search returns results from all SharePoint

Running X1 8.2 against SharePoint 2013.
I purchased X1 for personal use at work.

The issue is that a search finds results across many SharePoint Clients rather than the one I ask for.

For example, the URL's I entered into the SharePoint Data Source are all of the format:

(deleted)
etc


So in X1, I click on (say) AAA and enter my search criteria.
The results also include those in BBB and sites I don't even want.

Have I misunderstood how the SharePoint Data Source(s) work?
