You may not, however, want to use this option in a database in which documents are accessed infrequently or there is no last accessed date to track, for example, in a help desk application.
但是，对于另外一些数据库，如果数据库中的文档访问得比较少，或者没有可跟踪的最近访问日期，例如咨询台应用程序，那么您可能又不想使用这个选项。
The “use-by” or “best if used-by” date indicates the last day that the item is at its best quality as far as taste, texture, appearance, odor, and nutritional value. The decline after that is gradual.
“有效使用期”或“最好于该日期前使用”表示的是该产品在这个日期前，从口感、质地、外观、气味和营养价值等各方面保质着最佳质量，过期之后质量就会逐渐下降。
Mary: Okay, what is the last date of use? Do you remember?
玛丽：好的，您记得您最后使用是哪一天吗？
