FTS Index Size

Are there any references that help with estimating the size of a FTS index, or the whole catalog? I'm trying to do some capacity planning, and can't find anything to help me guess how much disk I'll need.
Unfornitually I haven't seen anything out there on how to do capacity planning for FTS.|||This is surprising to hear, as I thought FTS was a first-class, well-supported feature.

Hi Mike,
Nope, it hasn't been a first-class index in the same perspective as clustred or non-clustred index. However, that will change with the next release of SQL Server 2008, codename Katmai. I've long ago advocated this while a FTE, but alas it has taken many years to occur.

Regards,
John

|||Hi, John.

I'm not worried about it being a first-class index. I'm worried about it being a first-class feature. That is: something that's well-supported and usable in enterprise applications. If there's no documentation about how to do capacity planning for a deployment, it's hard for me to think that FTS is a first-class feature.
