Inside a search configuration under "Icon and Display" there is a field called Default Result Row Template.
This field will be used to show the results.
In this example, the following templates are used:
Projects
<div class="u-flex u-align-items-center">
<div class="margin-right-sm">
<span class="fa fa-search" style="margin-top: 2px; color: #94a3b8;" aria-hidden="true"></span>
</div>
<div class="u-flex-grow-1">
