Using New Spotlight in Lion (What does it find/not find?esp iPhoto

Question

I was reading a Lion review and trying the different new things in Lion it was talking about...one of which was the extensive search capability of Spotlight in the upper right hand corner.  But Im not sure if I'm doing something wrong or if it's not working properly.  It says it searches for images...but when I type in a word that for example is either a keyword, description or even title name for a photo in iphoto, it does NOT come up in the search.  For example, I tried on a new pair of eyeglasses named Zagg...Ive got photos that have that in the actual name, others in the description or keyword...I type in Zagg in Spotlight and no photos come up.  If it's searching for images, shouldn't it search for images in iphoto?  Seems weird.  If I type in a photo name from my old PC files (ie 000_124), that comes up in Spotlight...but apparently not Keywords or words in Descriptions?  This would seem like a glitch as I thought the whole reason for putting info on your photos - whether keywords, descriptions, actual names of files was so you could find them.
On the other hand, I find that it found photos that I didn't even have in iphoto or knew were on my system.  I typed in a person's last name and all of the sudden photos they might have sent me years ago via gmail (that were not labeled with their name at all) came up.  At first, I couldnt figure out where they were coming from as I didn't even recognize them but then I used the "SHOW ALL IN FINDER" button, and figured out that these were photos in a gmail and I guess because I imported gmail into imail, they came up...but it was wierd because I searched for the person's last name (which is part of their email address) and these photos (which did not have their name in the file name) came up.  And the photos are not in iphoto.
And yet photos that did have the name I was searching for in the file - either the name itself or a keyword - did not come up in Spotlight.
So when Spotlight says it searches for images, are those not iphoto Images?  It is not making sense to me as there seems to be some incompatibility between the Spotlight search and just a plain iphoto search.   Why wouldnt it all be integrated?

Answer 1

ok, I guess I was confused because it said it searched for images, and to me, images are photos.
If found iphoto photos based on number titles like 100_005 and such but not based on actual words that were used either as the file's name "John in Toronto" or descriptions, keywords etc
