除了要比较长度和索引值是否相等之外，还必须检查是解析后的nullNumber还是一个空的输入字符串(或长度为0)。
In addition to comparing the length and index values for equality, you must also check for either a null Number after parsing or an empty input string (" "or length of zero).
这说明，该函数必须在一个涉及比较操作并且引用了索引扩展hash _ index的搜索方法“equals”的表达式中使用。

为了展示这一点，将它与计划中第5号索引扫描上使用的谓词相比较，它针对子表中惟一的索引列。
To illustrate this, compare it to the predicate that is applied to the index scan numbered 5 in the plan, which is on the one and only column of the index on the child table.
为进行比较，让我们对文件数据库执行类似的索引搜索(使用了一些额外的搜索术语以使结果列表保持合理)。
For comparison, let's perform a similar indexed search against a file database (some additional search terms are used to keep the result list reasonable).
它的默认值是 Integer.MAX_VALUE，将这个参数设置为比较大的值可以提高索引效率和检索速度，由于该参数的默认值是整型的最大值，所以我们一般不需要改动这个参数。
The default value is Integer.MAX_VALUE. Large values are better for batched indexing and speedier searches.
通过将第一个索引与图4中所建议的索引进行比较，我们认识到，它是已有索引中某一个索引的子集。
By comparing the first index to the recommended ones in Figure 4, we realize that it is a subset of one of the existing indexes.
不允许使用大对象作为索引键，因为一般情况下不能够对大对象进行比较和排序。
