Fulltext query fails with "The content index is corrupt." on sql server 2005

What are my options here, does a repair exist or do I have to delete and rebuild the entire index?

I am afraid you will need to rebuild your entire index. There is no such option as 'repair'.

Please, feel free to contact me letting me know which operations toke place in order to have this corrupted status, as it is not common indeed.

Thanks.
