Projo defines exactly ONE custom SearchParameter. The rest of the project relies on HAPI's stock search parameters.
| Property | Value |
|---|---|
| URL | https://projo.evoleen.com/fhir/SearchParameter/CommunicationRequest-web-answer-token |
| Code | web-answer-token |
| Base | CommunicationRequest |
| Type | string |
| Expression | CommunicationRequest.extension.where(url = '…/web-answer-token').value |
The web-functions sweeper auto-creates this SearchParameter on first tick. After create/update of the SearchParameter, it triggers a $reindex on CommunicationRequest so existing instances pick up the new index.
Web-functions use this parameter to look up the CommunicationRequest a patient is submitting answers for, given the bearer token carried in the web POST.
Projo relies on HAPI's stock search parameters. Notably, HAPI does NOT auto-index CommunicationRequest.about (referenced internally as HAPI-0524). This is why the CR↔Task link is carried via Task.output[] instead of relying on ?about= searches.
Communication?identifier=<wamid-system>|<wamid>
Prevents duplicate inbound WhatsApp messages from creating duplicate Communications.
Communication?recipient=...&status=in-progress,completed&_sort=-sent&_count=1
Fetches the most recent Communication for a recipient within the 24-hour WhatsApp messaging window.
CommunicationRequest?recipient=Patient/{id}&status=active
Looks up any active CommunicationRequest targeting a given patient.
CommunicationRequest?status=active&category=identity-resolution-required
Used by the identity-resolution-events subscription to surface CRs that require identity resolution.
CommunicationRequest?status=completed,revoked&category:not=identity-resolution
Used by the cr-status-events subscription to track terminal state transitions on CommunicationRequests.
CarePlan?status=active&_tag:not=careplan-scheduling|scheduled
Used by the careplan-bootstrap subscription to pick up active CarePlans that have not yet been scheduled by Fire Arrow.
Organization?_tag=managed-subscription|<code>
Each app's sweeper reconciles its own Subscription by _tag search (always indexed in HAPI), rather than by criteria.
Observation?identifier=<extracted-resource-system>|<value>
Prevents duplicate Observations from being created by the extraction pipeline for the same source resource.
