usefully

I resolve to index data usefully.

我决心有效地索引数据。

More usefully, you can combine it with other elements in order to support more complex output and filtering.

更有用的是，您可以将它与其他元素组合，以支持更复杂的输出和过滤。

Even more usefully, you can copy files into the standard output and, then using pipes, you can extract the files from the standard input and copy the files from one location to another.

更有用的是，您可以将文件复制到标准输出，然后可以使用管道从标准输入中提取这些文件，并将它们从一个地方复制到另一个地方。
