Hii everybody,

We have implemented the fhirbase with pgsql and plv8 to support all the FhirbaseAPI related queries.

fhir_search

Search with queryString

SELECT fhir_search('{"resourceType": "Patient", "queryString": "name=smith"}');

This query is working fine and giving output as expected; We now have a requirement for searching all the patients whose name!=smith

When running the query like

SELECT fhir_search('{"resourceType": "Patient", "queryString": "name<>WILLIAMONE"}');

It is giving error as

ERROR: TypeError: Cannot call method 'split' of undefined

DETAIL: plv8_init() LINE 3912: return x.split(',').map(parse_one_value);

********** Error **********

ERROR: TypeError: Cannot call method 'split' of undefined

SQL state: XX000

Detail: plv8_init() LINE 3912: return x.split(',').map(parse_one_value);

Could anybody suggest any fix for this type of error or how to exactly implement a search query with NOT EQUAL constraint on any attibute
