Search refernce on external resource?

Hey there,

Can external reference resource be searched?

For example, let’s say I have an Observation resource and the subject property has a value of ‘’. If a user does search with ?, this should match.

However, if the user search for ?subject=Patient%2F123 or ?subject:Patient=123, should this also match? From my service, I have no context of what the base URL of that external service is.


As per, both of those will work. Though don’t make the assumption that the same resource will have the same id on different servers.

Thanks Lloyd. I wasn’t sure if that was applicable to external URLs or not when I first read the spec but I just read it again and it makes sense that the matching can be done regardless of whether it’s internal or external URL.
