我的存储过程文本搜索有问题

Question

我被困住了 - 我有一个很好的小文本搜索器，我已经放在一起了。

我意识到我需要在存储存储过程的各个文本块中计算 lnie，所以我想我已经找到了一种方法来做到这一点。

但它并没有在存储过程中获取搜索词的每个实例 - 我认为这是同样的原因......搜索词跨文本边界拆分。

我已经查看了如何更改我的查询 - 我正在空白。改变它所涉及的技能超出了我的范围！

你的 where 子句似乎有问题，这一点在这里

(
    (CHARINDEX(@searchString, SC.text) > 0
    AND CHARINDEX(@doesNotContain, SC.text) = 0)
    --OR
    --(SO.type = 'U'
    --AND CHARINDEX(@searchString, SO.name) > 0
    --AND CHARINDEX(@doesNotContain, SO.name) = 0)
