In your context, you should be using:

if( $this->fullSearchForm->get('title')->getValue()) {
    echo 'OK';
}

Because empty checks if a variable is set and not falsy, but a function's return value is always "set" so basically it's just a check for falsiness.

empty operates on variables, NOT functions.
