改为
虽然 nested query 只能返回父级文档，但是父子文档本身是彼此独立并且可被单独查询的。
是否更通顺一些？
我们使用 has_child 语句可以基于子文档来查询父文档，使用 has_parent 语句可以基于子文档来查询父文档。

按照原意 翻译会更好一些吧
返回父文档 type 是 branch 的所有子文档

| `has_parent` query 也支持 `score_mode` 这个参数，((("score_mode parameter")))但是该参数只支持两种值： `none` （默认）和 `score` 。因为每一个子文档都只有一个父文档，对子文档而言并不需要在多个评分中进行筛选，因此 `score_mode` 就很简单，取值仅为 `score` 和 `none` 。 |

这个query 是否应该翻译为中文？
下面这个改成如下是否更通顺？
每个子文档都只有一个父文档，因此这里不存在将多个评分规约为一个的情况，取值仅为 使用分数 ( score ) 和不用( none )。
| query no longer supports the `score_mode` parameter. Because it is merely | ||
| including/excluding documents and not scoring, the `score_mode` parameter | ||
| no longer applies. | ||
| 当不需要评分时（例如：在一个 `filter` 查询语句中），`has_parent` 不支持 `source_mode` 参数。因为 filter 查询的结果仅是存在或者不存在并且不需要评分，因此 `source_mode` 这个参数也就不需要了。 |

当 has_parent 查询用于非评分模式（比如 filter 查询语句）时，score_mode参数不再起作用。因为这种模式只是简单地包含或排除文档，没有评分，那么 score_mode 参数也就没有意义了。
