Example:

Usage search for "MyConstant" would not return the comment position even when executed with the enabled "search for text occurrences" option:

class MyClass {
   /**
    * @CUSTOM_ANNOTATION: ClassWithConstant::MyConstant
    */
   private $property;
}

class ClassWithConstant {
    const MyConstant = 1;
}
