I have full-text running on one database only.  This index seems to have
issues about once every couple of weeks.  Normally, a search can be done (via
webpage) on a keyword - and it works fine.  But there are times that no
keyword (or other options) searches will work.  The only option that is
searchable is "records updated in the last x number of days".  So it's like
the full-text searching 1/2 works.

I have ran the stored procedure to ensure FTS was installed properly.
The MSSearch server is running under the local system account (as it should
be per MS).
I have deleted and rebuilt it complete.  I have tried to rebuild the index
via the wizard and by right-clicking on the Full-Text Catalog --- neither
fixed the issue.
I've ran the stored procedure to ensure it was enabled.  

Anyone have any idea why my FTS will work completely one day and work "a
little" the next?

Thanks!
