Gmail Official blog giving out the tips and tricks to find a specific email with Gmail.
I should agree they have one of the best search facilities to search emails. It searches not only the subject or email address but the content of the email as well. Also, it will pick up from my chat log as well.
I never had to go that deep (as mention in the gmail blog) to find an email in my inblox. I just use key word combination and withing few clicks I can find the email. I think general search is really cool. What do you think?
However if you are interested finding a specific email you better read this post.
