我正在构建一个api.ai代理，但我很难date-period正确理解无界参数。
例如：
before 2000被解释为["2000-01-01/2000-12-31"]after 1999被解释为["1999-01-01/1999-12-31"]after January 2007被解释为["2007-01-01/2007-01-31"]
这让我认为只有日期（2000/ January 2007）用于计算日期范围，忽略副词（before/ after）。
有没有办法理解

The before and after isn't matched, you are right.
You can add a custom entity, like temporal preposition, to deal with this.
before: prior to, previous to, earlier than, preparatory to, in preparation for, preliminary to, in anticipation of, in expectation of; in advance of, ahead of, leading up to
after: following, subsequent to, succeeding, at the close/end of, in the wake of, later than
You may create a composite entity (see in the docs).
There you can compose the new preposition entity with the sys.date entity.
So you will bound them together logically.
