If true, include full span details for each trace. This significantly increases response size and query latency, especially with large page sizes. Prefer fetching spans lazily for individual traces when possible.

Deprecated: use filter=error_count > 0 or filter=error_count == 0. Filter by trace error status. If true, only return traces that contain at least one span with status_code == ERROR. If false, only return traces with no errored spans. If omitted, traces are not filtered by error status.

Inclusive lower bound on trace latency in milliseconds. Deprecated: use filter=latency_ms >= N.

Inclusive upper bound on trace latency in milliseconds. Deprecated: use filter=latency_ms <= N.

Trace filter expression, as documented at https://arize.com/docs/phoenix/tracing/how-to-tracing/filter-expressions. Combined with other filters using AND. Empty expressions do not filter. Invalid expressions return 400.
