Custom Search Parameter always returns 0 results for the custom resource

[Neeraj Kumar]

Hi,

I am using Hapi-Fhir version 5.3.0-SNAPSHOT. I have implemented the 'CustomResource' and It's successfully getting created and search by 'id' is also working. The JSON structure for 'CustomResource' is,

{

    "resourceType": "CustomResource",

    "dogs": "Himalayan Sheepdog",

    "customDataType": {

        "date": "2020-02-01",

        "kittens": "Juvenile cat"

    }

}

I have created a custom search parameter for the string field 'dogs'. The JSON structure for 'SearchParameter' is,

{

    "resourceType": "SearchParameter",

    "id": "cr-dogs",

    "title": "Custom Resource Dogs",

    "base": [

        "CustomResource"

    ],

    "status": "active",

    "name": "dogs",

    "code": "dogs",

    "type": "string",

    "expression": "CustomResource.dogs"

}

URL: http://localhost:8080/fhir/PARTITION-10/CustomResource?dogs=Himalayan Sheepdog

But when I hit this search URL It always returns 0 results. Any idea what's wrong I am doing here.
