Use the common fields for identity and promoted evidence, then open the relevant protocol range for protocol-specific fields. Dataset: `services` Endpoint identity, attribution, observations, fingerprints, HTTP, TLS, and tags. Protocol-specific fields beginning with A through F. Protocol-specific fields beginning with G through L. Protocol-specific fields beginning with M through R. Protocol-specific fields beginning with S through Z. To use a service field while searching hosts, add the `services.` prefix. For example, `fingerprints.ja4s` becomes `services.fingerprints.ja4s`.
