我正在搜索一篇新闻报道。 2个相关列为ArticleTitle和ArticleText。当我想搜索特定术语的文章时，我开始使用
column LIKE '%term%'。
然而，这给了我很多关于锚链接内的术语的文章，例如<a href="example.com/*term*>可能会返回一篇不相关的文章。
然后我切换到
column LIKE '% term %'。
此查询的问题是它没有找到文章的标题或文本以术语开头/结尾。它也与我{I} term-或term's之类的内容不匹配。
似乎我想要的查询应该可以做这样的事情
'%[^a-z]term[^a-z]%
这应该排除锚链接中的术语，但不包括其他所有内容。我认为这个查询仍然排除了以该术语开头/结尾的字符串。有更好的解决方案吗？ SQL-Server的FULL TEXT INDEXING是否解决了这个问题？
此外，将ArticleTitle和ArticleText存储为无HTML列是一个好主意吗？然后我可以使用'%term%'而无需获取锚链接。这些将是2个额外的列，因为最终我将需要原始的HTML用于格式化目的。
感谢。

允许您像您所描述的那样定义类似Regex的模式。
更好的选择是使用fulltext search：
LIKE正确利用索引（WHERE CONTAINS(ArticleTitle, 'term')
查询速度慢），并在搜索算法中提供其他好处。
此外，您可能会受益于将文章的纯文本版本与HTML版本一起存储，并在其上运行搜索查询。
