Which free email provider provides the best search through emails?

like, when I search on yahoo I get a bunch of non-sense results, I want the opposite of that, which free email provider should I go to? gmail because is googles?|||I would suggest gmail. In the past i have used alot of different email providers but now use gmail because it has good spam filtering, lots of storage space, and it is simple to use. i also think it has free video chat.
