Since a graphic character is always 2 bytes long, the maximum graphic length that can be indexed is 510 graphic characters, and the column can be defined as VARGRAPHIC (510).
与字符串相关的一些典型的检查，会验证空字符串的长度是否为 0，访问范围超出索引是否导致错误消息或异常，等等。
Some of the typical string-related checks would validate whether an empty string has 0 length, accessing out-of-index results in an error message or exception, and so on.
例如，如果用户要输入一个字符串，用它来搜索某个索引，则必须过滤掉可能会造成越界搜索的不合适的通配符，这是很重要的。

与字符串相关的典型检查包括检查空字符串的长度是否为 0以及访问范围超出索引是否导致错误消息/异常。
Some of the typical string-related checks include verifying that an empty string has 0 size and accessing out of index from the string results in an error message/exception.

This article demonstrated how DB2 index extensions can be used to index texts or strings.
正如您在表3中所看到的，字符串谓词只能由varchar类型的xml索引进行计算，而数值谓词只能由double类型的索引进行计算。
As you see in Table 3, a string predicate can only be evaluated with an XML index of type VARCHAR, while a numeric predicate can only be evaluated with an index of type DOUBLE.
使用该方法验证的关键在于将更新过的索引和初始输入字符串的长度进行比较。
The key to using the method for validation is to compare the updated index to the length of the original input string.
字符串以单词为界被划分成单个单词，这些单词形成了索引条目。
The strings are split at word-boundaries into separate words, and those words form the index entries.
该索引包含实际字符串的散列值，只能用于等式谓词，不能用于范围谓词。
This index contains hash values of the actual strings and can be used for equality predicates only, not for range predicates.
也就是说，这是一个无序容器，按字符串而不是整数来进行索引。
That is, it's an unordered container, indexed by strings rather than integers.

The associated values array is generated inside the hash function and is indexed using keysig characters.
因为搜索字符串也需要以处理索引文本的方式进行处理。
Because the search string has to be processed the same way that the indexed text was processed, it is crucial to use the same Analyzer for both indexing and searching.
