Lion Mail search a downgrade?
I've always been satisfied with the Mail.app search facility, until Lion. It works differently, and I can't locate things that were easily located before.
For instance, if I had searched "buy.com" prior to Lion, a list of the messages to and from buy.com would appear, even if "buy.com" only appeared in the address. Now a search yields nothing, even though I have messages from buy.com in my Mail folders.
Is there a way to cause Mail to search as effectively as it did before Lion, or is this a downgrade? This is definitely not an isolated issue for me. I am now constantly not able to locate messages I now are either in the Inbox or another folder, even when I search words that are in the body of a message.
