// The search result ID is comprised of the extension ID and the
extension-supplied item ID. This is to avoid naming collisions for results of
different extensions.

Optional: It may be a good idea to move this concatenation and comment into a
stand-alone function (e.g., MakeSearchResultId). Not really for reuse, but just
so it's clearly visible that this is going on, instead of being hidden away in
the constructor.
