Comment 6 for bug 1368336

If I got the description from James right, it's more complicated than just calling refresh().

Refresh() will re-execute last search, clear current results and replace them with new results, even if they are the same. What I think is expected now is to only update the view when new content is available. This new requirement means substantial change to how scopes plugin handles results: currently it clears old results and displays new results incrementally as they arrive from scope; instead it will have to buffer incoming results up till the decision can be made whether this is same result set as before, or new (in many cases it means delaying them till search finishes).
