I installed Mac OSX Lion few days ago, why does it index my computer in Spotlight?

-The thing is, it indexed my computer once Lion finished installing. But its doing it again right now, why? Does it keep doing this every time you start up your computer? Because if so then I really can't use Spotlight at all like before.Not enough information available yet about what is working correctly and what is not out on the web..at least smaller things with definitive answers. Try checking the Help section in Lion when you are on the desk top. Click help and type in the word spotlight reindexing and see what you get.
