6.3.2 From / Size 分页查询

通过 from 和 size 就可以执行分页查询。from 指明了分页查询返回的结果的起始位置，而size参数则指明了分页查询的页容量。

这两个参数既可以以 request parameters 的形式来设置，也可以在 search body 中设置。默认情况下 from 值是 0，而 size 值是 10。

{
    "from" : 0, "size" : 10,
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}

但要注意的是 from + size 不能超过索引的 index.max_result_window 值，该值默认是 1000，你可以查阅 Scroll API 来了解另一种更有效的 do deep scrolling (深度滚屏查询)的方式。

Pagination of results can be done by using the from and size parameters. The from parameter defines the offset from the first result you want to fetch. The size parameter allows you to configure the maximum amount of hits to be returned.

Though from and size can be set as request parameters, they can also be set within the search body. from defaults to 0, and size defaults to 10.

{
    "from" : 0, "size" : 10,
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}

Note that from + size can not be more than the index.max_result_window index setting which defaults to 10,000. See the Scroll API for more efficient ways to do deep scrolling.
