es 深度分页问题

背景

使用es的from/size进行常规的分页操作时，有一个max_window_size限制，大小默认是10000，当from+size > 10000时，会有如下报错：

    "error": {
        "root_cause": [
            {
                "type": "query_phase_execution_exception",
                "reason": "Result window is too large, from + size must be less than or equal to: [10000] but was [10001]. See the scroll api for a more efficient way to request large data sets. This limit can be set by changing the [index.max_result_window] index level setting."
            }
        ],
        "type": "search_phase_execution_exception",
        "reason": "all shards failed",
        "phase": "query",
        "grouped": true,
        "failed_shards": [
            {
                "shard": 0,
                "index": &#
