Topic: partial match on code (token search)
Simone Heckmann (Aug 22 2016 at 14:28):
Am I right to assume, that token search never returns partial matches? I mean, we wouldn't want the search for identifier "1" to return a result with identifier "11", right?
But what if I want to search for a partial code, e.g. search for all ICD-10 diagnoses that start with "F17". Is that possible? Is there a modifier for that (like, the opposite of ":exact")?
If I read this correctly, the :text modifier does in fact do a partial search but not on the value of the code but instead on the display (which may not contain the actual code).

you're looking for subsumption, not partial match
Simone Heckmann (Aug 23 2016 at 07:24):
Um. yes, that could work. Assuming I have the whole ICD-10 catalogue as a structured ValueSet.
Ok next use case: In Germany, we have identifiers for Health-Care providers in which the first two digits have a meaning (=association with an administrative district) and I was wondering if there was a way to search for all instances of Organization where the identifier starts with "xx". (I'd guess that there are other identifier systems out there, where prefixes have a search-worthy meaning?)

assuming you have a terminology server that understands ICD-10. yes
Grahame Grieve (Aug 23 2016 at 08:04):
and no, we haven't defined anything like that. I guess you'd want to define a custom modifier. It doesn't sound like common practice to me

If your code system and terminology server provided a filter like "concept regex 'xx.*'" then it might be possible
