What you want is:
<logic:present name="results" scope="session">
This will check for a bean stored under the name 'results' in session scope.
${sessionScope.results} evaluates to the bean itself. The logic tag
receives *that bean* where before it received a String. I believe
that the logic tag would then convert that bean to a String and look
for an object stored under that name, instead.
Instead of dealing with all of this, just try the following JSTL:
<c:if test="${not empty sessionScope.results}">
