Boolean search param combination for fhir_search

[Subhrajyoti Moitra]

Hello Team,

I have been using the latest fhirbase from github and able to create/update/search resources.
I am unable to combine queryString params something like, "give me all observations for a particular patient which belongs to a particular category"

SELECT fhir_search('{"resourceType":"Observation","queryString":"category=vital-signs and subject=Patient/65352c58-3260-453d-867f-fc8da03916f6"}');

This yields not results. How do I combine 2 different params in AND or OR clauses?

Please guide. Any pointers to how to solve this?

Thanks,
Subhro.

Hi

You have to pass HTTP query string as described in FHIR spec - https://www.hl7.org/fhir/search.html. In your case replace " and " with "&". And you can search only by SearchParameters, which you can find in concrete ResourceType specification or by looking up searchparameter table.

Hello Nicola,

Yes, I managed to make it work,

SELECT fhir_search('{"resourceType":"Observation","queryString":"category=vital-signs & subject=Patient/65352c58-3260-453d-867f-fc8da03916f6"}');

The above link has some hints on how to solve it.

Thanks again for your time,
Cheers,
