[IC] results.html - different display for first 2 search results

[interchange-users@interchange.redhat.com]

IC 4.8.3

I am trying to modify the default foundation results.html page. Would like
to display a thumbnail and description for the first 2 items in the
search-list and have the rest of the returned results remain as they are.

Is there an example of this somewhere?

What tags should I be looking at?

I am guessing there is an increment value that I should be able to use to
place a condition on?
