If you're talking about not wanting the "Categories" section showing up when you don't have any category matches, that's not problem. Just edit your search_results.html template and do something like:
<%if category_results%>
<!-- Category section here -->
<%category_results%>
<%endif%>
<!-- Links -->
<%if link_results%>
<!-- Link section here -->
<%link_results%>
<%endif%>

Code:
<!-- Categories --> <%if category_results%>
<!-- Category section here -->
<%category_results%>
<%endif%>
<!-- Links -->
<%if link_results%>
<!-- Link section here -->
<%link_results%>
<%endif%>
