Topic: Searching by number of elements
Vladimir Shapira (Apr 06 2022 at 18:26):
Hello experts,
I'm playing with searching requests on Hapi server.
I was wondering if its possible to search by number of elements in the resource?
Something like - get all patient resources with 20 or more elements/fields in the resource
Or - get all patient with less than 10 elements in the resource?
Thanks ahead for any info and help,
Vlad

I don't imagine that it would be. That's very subject to interpretation. For instance you have an array of names. Is it 1 element because the array exists? Is it 2 because the array exists and it has 1 slot filled? Is it 4 elements because it exists, has 1 slot, slot 1 has family and suffix attributes populated? .......

Hi, your use-case is not covered by the FHIR spec and hapi.
Out of curiosity, what is the use-case for such a search?

I expect that might be possible with a custom search parameter using the descendants().count fhirpath expression

Hi,
Thanks for replies for this.

Probably no specific use case for this, just testing different searches.
Most responses i get from Hapi are simple examples, for example for patient are just name and last name.
Was thinking if there is such a search possible, it will find me patients with more data/complex examples - just to have more diversity of returned data. Patient is just example of resource, yeah i could use patient specific parameters, but these will not work for other resources.

Yeah, I actually expect @Brian Postlethwaite 's idea would work if you created a search parameter of type number. Definitely have never tried this though...
