    Filter the lineage information under summary base directory according to search condition.

    Users can filter and sort all lineage information according to the search
    condition. The supported filter fields include `summary_dir`, `network`,
    etc. The filter conditions include `eq`, `lt`, `gt`, `le`, `ge` and `in`.
    If the value type of filter condition is `str`, such as summary_dir and
    lineage_type, then its key can only be `in` and `eq`. At the same time,
    the combined use of these fields and conditions is supported. If you want
    to sort based on filter fields, the field of `sorted_name` and `sorted_type`
    should be specified.

    Users can use `lineage_type` to decide what kind of lineage information to
    query. If the `lineage_type` is not defined, the query result is all lineage
    information.

    Users can paginate query result based on `offset` and `limit`. The `offset`
    refers to page number. The `limit` refers to the number in one page.

    Args:
        summary_base_dir (str): The summary base directory. It contains summary
            directories generated by training.
        search_condition (dict): The search condition. When filtering and
            sorting, in addition to the following supported fields, fields
            prefixed with `metric/` and `user_defined/` are also supported.
            For example, the field should be `metric/accuracy` if the key
            of `metrics` parameter is `accuracy`. The fields prefixed with
            `metric/` and `user_defined/` are related to the `metrics`
            parameter in the training script and user defined information in
            TrainLineage/EvalLineage callback, respectively. Default: None.

            - summary_dir (dict): The filter condition of summary directory.

            - loss_function (dict): The filter condition of loss function.

            - train_dataset_path (dict): The filter condition of train dataset path.

            - train_dataset_count (dict): The filter condition of train dataset count.

            - test_dataset_path (dict): The filter condition of test dataset path.

            - test_dataset_count (dict): The filter condition of test dataset count.

            - network (dict): The filter condition of network.

            - optimizer (dict): The filter condition of optimizer.

            - learning_rate (dict): The filter condition of learning rate.

            - epoch (dict): The filter condition of epoch.

            - batch_size (dict): The filter condition of batch size.

            - device_num (dict): The filter condition of device num.

            - loss (dict): The filter condition of loss.

            - model_size (dict): The filter condition of model size.

            - dataset_mark (dict): The filter condition of dataset mark.

            - lineage_type (dict): The filter condition of lineage type. It decides
              what kind of lineage information to query. Its value can be `dataset`
              or `model`, e.g., {'in': ['dataset', 'model']}, {'eq': 'model'}, etc.
              If its values contain `dataset`, the query result will contain the
              lineage information related to data augmentation. If its values contain
              `model`, the query result will contain model lineage information.
              If it is not defined or it is a dict like {'in': ['dataset', 'model']},
              the query result is all lineage information.

            - offset (int): Page number, the value range is [0, 100000].

            - limit (int): The number in one page, the value range is [1, 100].

            - sorted_name (str): Specify which field to sort by.

            - sorted_type (str): Specify sort order. It can be `ascending` or
              `descending`.

    Returns:
        dict, lineage information under summary base directory according to
        search condition.

    Raises:
        LineageSearchConditionParamError: If search_condition param is invalid.
        LineageParamSummaryPathError: If summary path is invalid.
