Reference documentation and code samples for the Google Cloud Talent Solution v4 API class RequestMetadata.
Meta information related to the job searcher or entity
conducting the job search. This information is used to improve the
performance of the service.
Only set when any of
[domain][google.cloud.talent.v4.RequestMetadata.domain],
[session_id][google.cloud.talent.v4.RequestMetadata.session_id] and
[user_id][google.cloud.talent.v4.RequestMetadata.user_id] isn't available
for some reason. It is highly recommended not to set this field and provide
accurate [domain][google.cloud.talent.v4.RequestMetadata.domain],
[session_id][google.cloud.talent.v4.RequestMetadata.session_id] and
[user_id][google.cloud.talent.v4.RequestMetadata.user_id] for the best
service experience.
Required if
[allow_missing_ids][google.cloud.talent.v4.RequestMetadata.allow_missing_ids]
is unset or false.
The client-defined scope or source of the service call, which typically
is the domain on
which the service has been implemented and is currently being run.
For example, if the service is being run by client <em>Foo, Inc.</em>, on
job board www.foo.com and career site www.bar.com, then this field is
set to "foo.com" for use on the job board, and "bar.com" for use on the
career site.
Note that any improvements to the model for a particular tenant site rely
on this field being set correctly to a unique domain.
Required if
[allow_missing_ids][google.cloud.talent.v4.RequestMetadata.allow_missing_ids]
is unset or false.
A unique session identification string. A session is defined as the
duration of an end user's interaction with the service over a certain
period.
Obfuscate this field for privacy concerns before
providing it to the service.
Note that any improvements to the model for a particular tenant site rely
on this field being set correctly to a unique session ID.
Required if
[allow_missing_ids][google.cloud.talent.v4.RequestMetadata.allow_missing_ids]
is unset or false.
A unique user identification string, as determined by the client.
To have the strongest positive impact on search quality
make sure the client-level is unique.
Obfuscate this field for privacy concerns before
providing it to the service.
Note that any improvements to the model for a particular tenant site rely
on this field being set correctly to a unique user ID.
