Topic: search on extension element

Is it possible to search against an core extension? For example in Patient there is an extension for mothersMaidenName. Is this just an element within the Resource, or is there a way to search given a mothers maiden name?
Josh Mandel (Apr 25 2017 at 02:57):
There's a way to search, but not generically: the server needs to support a search parameter like mothers-maiden-namethat specifically indexes this extension
Lloyd McKenzie (Apr 25 2017 at 13:26):
You can define - and expose support for - searching using any arbitrary search parameter using the SearchParameter resource
John Moehrke (Apr 25 2017 at 14:17):
okay. I thought that there was a way for an extension to indicate that it was searchable. Especially useful/reasonable with core extensions.
Lloyd McKenzie (Apr 25 2017 at 14:33):
All elements are theoretically searchable - both core and extension. And the same element could have 6 or 7 different SearchParameters defined for it that all have different behavior - for example Patient.name could have a search parameter that did soundex, one that did a custom phonetic search, one that only looked at given and family names, etc. So knowing the element isn't enough to define the SearchParameter.
