Vista indexing process killing Battery Life

I found a note from one of the i7210 owners at Origami Project that I think that deserves all our attention:

I've been struggling with poor battery life running Vista on my eo i7210. I've been averaging about 1:40 which is pitiful. Well, yesterday I made a change and have been getting closer to 2:30 (the advertised battery life) under Vista. I found that the indexing service was constantly running and reving up the CPU and memory. By disabling the service I am finding the unit runs cooler and longer on battery. Of course this means that I am not able to use Vista's built in search feature, but that's okay because I'm not a big fan of it anyway.

The indexing process in XP has been all time a CPU Performance killer and I always have it disabled. I have not check it yet in my eo v7110 with Vista but probably this user is right, Indexing could be a bad idea.
