- `optimization_id` string, uuid
- `types` string
- `name` string — Filter experiments by name (partial match, case insensitive)
- `dataset_deleted` boolean
- `sorting` string
- `filters` string
- `experiment_ids` string — Filter experiments by a list of experiment IDs
- `force_sorting` boolean — Force sorting even when exceeding the endpoint result set limit. May result in slower queries
