While Yahoo results are loaded first, the later appearing (same) results from smaller indizes are being removed as doublets. To keep these results "alive" and to keep the names of e.g. "DeuSu", "Scopia" etc. we could

• (desktop): write "Found by Yahoo, Scopia and DeuSu" or something similar
• (mobile): hide this information inside a title attribut (e.g.) to show it by touch event.

The goal should be to have the names of the smaller SEs more outstanding and more frequently.
