请注意，原始字符串中的 "not" 解释为操作符，而不是单词 "not"。

STOPLIST 'not and'

sure understand

'understand'.

请注意，由于 "not" 解释为短语 "i am" 和 "sure" 之间的操作符 (AND NOT)，所以会删除 "sure"。由于短语 "i am" 包含过短的术语而被删除，因此 AND NOT 条件的右侧 ("sure") 也被删除。这样将只留下 "understand"。

不对任何内容建立索引，因为没有长度等于或大于 20 个字符的术语。

这说明了 MAXIMUM TERM LENGTH 对 GENERIC 和 NGRAM 文本索引的不同影响；对于 NGRAM 文本索引，MAXIMUM TERM LENGTH 设置插入到文本索引中的 n 元语法词的长度。

搜索将返回空结果集，因为通过查询字符串无法形成 20 个字符的 n 元语法词。
