This is a dynamic query parameter name, used to filter endpoint response by its metadata field. The {schemaFieldId} template represents the schema id and field name concatenated together by a dot (.). In effect, it expands to the sub-template {schema-id}.{schema-field-name}. The {schema-id} template is the UID of a schema. The {schema-field-name} template is a path separated by the forward slash (/) (to allow for representation of nested objects).
The value of the query parameter is a CSV of strings appropriate for the given metadata field.
Valid options are:
metadata.{schemaFieldId}: string
has_metadata.{schemaFieldId}: true - Filter by the existence of a metadata field.
metadata.{schemaFieldId}.from: string (date) - Filter by a metadata date field (inclusive)
metadata.{schemaFieldId}.to: string (date) - Filter by a metadata date field (exclusive).
See the examples for each valid option:
metadata.schema:1.live_date_range
has_metadata.schema:1.live_date_range
metadata.schema:1.live_date_range/from
metadata.schema:1.live_date_range/to
