Combo SearchParameter question

I have made a combo search parameter (shown below). I added it successfully, but when reindexing I keep seeing the error "CompositeExtractor - skipping unsupported search parameter observation-search". Any idea what I'm doing wrong?

{
    "resourceType": "SearchParameter",
    "id": "observation-search",
    "status": "active",
    "name": "ObservationSearch",
    "extension": [
      {
        "url": "http://hapifhir.io/fhir/StructureDefinition/sp-unique",
        "valueBoolean": false
      }
    ],
    "code": "observation-search",
    "base": [
      "Observation"
    ],
    "type": "composite",
    "expression": "Observation",
    "component": [
      {
        "definition": "SearchParameter/Observation-based-on",
        "expression": "Observation"
      },
      {
        "definition": "SearchParameter/Observation-combo-code",
        "expression": "Observation"
      },
      {
        "definition": "SearchParameter/Observation-value-concept",
        "expression": "Observation"
      },
      {
        "definition": "SearchParameter/Observation-component-code-value-concept",
        "expression": "Observation"
      },
      {
        "definition": "SearchParameter/Observation-component-code",
        "expression": "Observation"
      }
    ]
  }

Probably this is an issue with one of the component search parameters. Currently the rules for them are:

- They can't be of type "composite" themselves

- They must have an expression defined

- That expression can not contain the "%resource" variable (I don't remember the reason for this rule for the life of me - but it's in there)

Cheers,

James

Thanks! One of the composites is itself a composite. If I wanted to include this, would I just need to add the fields from that composite in my original "new" index?

That should do it, yup.
