Topic: Search Parameter instance
Katie Wheatley (Apr 09 2019 at 08:21):
Please could colleagues confirm whether I have coded this instance of a SearchParameter correctly. It is designed to be a parameter to search on either the valueQuantity or the valueRange of ServiceDefinition.useContext.value. In particular, do the expression and xpath elements contain the correct code?
I have entered the comparators that I need.
<SearchParameter>
<id value="86aa11aa-41a1-411f-9596-2469ad6d9016"/>

This seems like something where you'd want to create a composite search criteria - i.e. one that combines both the code and value of useContext. Checking a range but knowing a range of "what" isn't going to be that helpful...
