SQL Server 2008 FREETEXT搜索停止工作

Question

我最近遇到一個問題，FREETEXT搜索在我的存儲過程中停止工作。

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

這已經工作了幾個月直到今天。我一直在嘗試了一些東西，那麼這工作是由我進入我的全文目錄，並在Category列刪除它，然後將它添加回來的唯一的事。

任何人都有這個問題，如果這樣做你知道它爲什麼發生？我們在若干表中的幾列上使用FREETEXT，我擔心它可能在別處不知情的情況下發生。

Answer 1

我使用這些查詢來監視我的全文索引的狀態。 在第一個查詢中，PopulateStatus應該是「0 - 空閒」。 在第二個查詢中，CrawlCompleted列應該爲「1」。
