Lion will at random have Spotlight re-index itself
When I originally installed Lion, Spotlight did it's usual re-indexing as it always does on the first run. After resetting the power management on my MBP 8,2 earlier today to see if it would relieve me of my battery woes, I caught on reset Spotlight attempting to re-index itself - but within 2 minutes it just stopped itself without me cancelling it. Between then and now I've shut down my laptop twice, and on the boot this time around Spotlight is re-indexing. I'm letting it run its course, but I am curious to see if anyone else is experience this.
It's a little annoying because it's killing my battery and making the fans go wild.
