Question

我最近遇到了FREETEXT搜索在我的存储过程中停止工作的问题。

SELECT ShowID
FROM Table
WHERE FREETEXT(Category, @Category)

这已经工作了几个月，直到今天。我一直在尝试一些事情然后唯一有效的方法是我进入我的全文目录并将其删除到Category列，然后重新添加。

有没有其他人有这个问题，如果是，你知道为什么会这样吗？我们在几个表中的几个列上使用FREETEXT，我担心在我们不知道的情况下它可能会发生在其他地方。

我使用这些查询来监控全文索引的状态。在第一个查询中，PopulateStatus应为“0 - 空闲”。在第二个查询中，CrawlCompleted列应为“1”。
