Search results with "pencil icon" – how to change this or replace with image?

Hi,

I’ve tried a search at the ENFOLD demo theme with “about” as keyword. The result is this:

• Where can I take influence on the icon in front of the search results?
• Where does this “pencil icon” come from and where can I change it?
• Why have some results an image in front of it?

At my own site (currently in maintanence mode) it is the same: I only have this “pencil icon” in front of each search result in this box.

And at this point another question:

when I click then at “view all results”, then at the page with the total search results, there are only numbers in front of the search results:

Is it possible to show there, for example, an own icon or an own image in the circle like in the search box (see screenshot above)?

By the way: I use the Relevanssi plugin.

Thanks.
