        Get Tasks (Historic) (POST) Queries for historic tasks that fulfill the given parameters. This method is slightly more powerful than the [Get Tasks (Historic)](https://docs.camunda.org/manual/7.18/reference/rest/history/task/get-task-query/) method because it allows filtering by multiple process or task variables of types `String`, `Number` or `Boolean`. The size of the result set can be retrieved by using the [Get Task Count (POST)](https://docs.camunda.org/manual/7.18/reference/rest/history/task/post-task-query-count/) method.
        Parameters:
        firstResult - Pagination of results. Specifies the index of the first result to return. (optional)
        maxResults - Pagination of results. Specifies the maximum number of results to return. Will return less results if there are no more results left. (optional)

        Get Tasks (Historic) (POST) Queries for historic tasks that fulfill the given parameters. This method is slightly more powerful than the [Get Tasks (Historic)](https://docs.camunda.org/manual/7.18/reference/rest/history/task/get-task-query/) method because it allows filtering by multiple process or task variables of types `String`, `Number` or `Boolean`. The size of the result set can be retrieved by using the [Get Task Count (POST)](https://docs.camunda.org/manual/7.18/reference/rest/history/task/post-task-query-count/) method.
        Parameters:
        firstResult - Pagination of results. Specifies the index of the first result to return. (optional)
        maxResults - Pagination of results. Specifies the maximum number of results to return. Will return less results if there are no more results left. (optional)
        historicTaskInstanceQueryDto - (optional)
        Returns:
        ApiResponse<List<HistoricTaskInstanceDto>>
        Throws:
        ApiException - If fail to call the API, e.g. server error or cannot deserialize the response body
