QPF Endpoint /search

New in version 1.1.

ESS provides an Quad Pattern Fragment (QPF) endpoint that can be used to perform a Podwide query (i.e., query within a Pod). The endpoint is available to Pod Owners, and others with appropriate access. You can further specify which applications can query the endpoint by granting specific applications appropriate access.

Alpha Feature

The QPF endpoint is currently available as an Alpha feature for on-prem ESS. The endpoint is available for testing purposes only and not for production use.

For details on query and response, see QPF specification.

See also Triple Pattern Fragment (TPF) specification.

QPF Endpoint

ESS uses the following as the default QPF endpoint:

https://fragments.<DOMAIN>/<Pod Name>/search

If your ESS deployment configuration uses a different endpoint, see Discovery.

For the available query parameters, see QPF Hypermedia controls.

Access Control

• Only Agents who have Control Read access to the root of the Pod, such as the Pod Owner, can access data from the QPF endpoint. You can further specify which applications can query the endpoint by granting specific applications appropriate access.

• The QPF endpoint requires an Authorization header with an Auth token.

Additional Information
