This parameter determines how many documents you can store in the original segment index and how often you can merge together the segment indexes in the disk.
这个参数决定了在Lucene的一个索引块中可以存放多少文档以及把磁盘上的索引块合并成一个大的索引块的频率。
After you add the documents to the index, don't forget to close the index by calling this method, which guarantees that the index changes are written to the disk.
当我们把文档添加到索引中后，不要忘记关闭索引，这样才保证Lucene把添加的文档写回到硬盘上。下面的一句代码演示了如何关闭索引。
The fourth line cleans up the index. IndexWriter physically deletes from the disk the documents that have been marked as deleted.
第4行对索引进行清理，清理过程中将把所有标记为删除的文档物理删除。
After the initial batch indexing is completed, make sure that there is twice as much free disk space as the Lucene index size.

For maximum indexing performance, the index should reside on a nonsystem disk that rotates at 10,000 RPM or greater.

It provides the basis for dealing with the on-disk file system, as it defines the file system's managing parameters (for example, total number of blocks, free blocks, root index node).
它是处理磁盘上的文件系统的基础，因为它定义文件系统的管理参数(例如，块的总数、空闲块和根索引节点)。

当从硬盘驱动器读写表和索引数据时，DB 2使用缓冲池来缓存它们。
For a long time researchers only focus on disk-based index, but research on memory-based index is of great value today because of the mass memory condition.
以往大部分学者都集中研究磁盘索引，但其实在目前大内存的环境下对内存索引的研究也是非常必要。
