The table is logically joined to itself, and the more selective non-leading index keys are applied as index bound filters to each unique combination of the leading key values.
首先在逻辑上将表与其自身连接，然后将更具有选择性的非起始索引键作为索引绑定过滤器，应用于起始键值的每个惟一的组合。
However, since XML columns cannot be part of the table partitioning key, any unique XML values index will have to be created as a global index.
然而，由于xml列不属于表分区键的一部分，任何唯一xml值索引必须创建为全局索引。
You can help speed up index maintenance by using a large buffer pool for the index tablespace, and, if possible, ordering the inserts so that the key values are ordered, not random.
如果为索引表空间使用较大的缓冲池，并且尽可能地将不同 insert排序，以便键值是排好序的，而不是随机的，就可以帮助加快索引维护。
In the path secondary index, the path and node values are key columns that allow efficient seeks when searching for paths.
在PATH辅助索引中，路径值和节点值是用于提高路径搜索效率的键列。
