SQL Server 2008 FREETEXT 搜索停止工作

Question

我最近遇到了一个问题，即 FREETEXT 搜索在我的存储过程中停止工作。

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，然后唯一有效的是我进入我的全文目录并将其从Category 列中删除，然后将其重新添加。

有其他人遇到过这个问题吗？如果有，您知道为什么会这样吗？我们在几个表的多个列上使用了FREETEXT，我担心它可能会在我们不知道的情况下发生在其他地方。

Answer 1

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