OK, some followups then:

- Is the index rebuilt from scratch every time, or should updates be fairly 
quick?  I just did a search on my inbox (about 10,000 messages), and I know 
I've done a search there in the past month - yet it either took many, many 
minutes, or it timed out.

- If I wrote a script to log in and search for something, and ran it every 
night through cron, would that achieve daily indexing?
