hi
the existing token search modifier are: :text :not :above :below :in :not-in :of-type

I d'like a new modifier called :maps-to in order to search for concepts or their equivalent.
Right now as far as I know, one have to: 1. ask for conceptMap resource to get those equivalent coding 2. feed the token list with them in the search.

I guess that could be done in one step for the client.

Thought ?

How do you index for that?

@Lloyd McKenzie
you mean index like RDBMS index ?

If servers are going to support the search parameter, they're going to want to index to ensure that searches can be efficient. This seems like a difficult thing to index on.

If you can index for :in and an arbitrary ValueSet, then indexing for a ConceptMap should not be any harder (I mean that as a desirable, not as assessment of the current state).
In order to support this efficiently with an external terminology service we'd want to be able to do "bulk translate" rather than the current single-code translate.

Additionally, :maps-to would also need to be able to account for the equivalence relationship in the ConceptMap - do you only want equivalent codes, or are broader than or narrower than valid?
