How can I search websites in mylot?SOS

Tweet

It's convenient to search websites on mylot directly when you are using it.But is there anyone can tell me how to use it more quickly?Take an example,I want to sign in my yahoo mail and I type yahoo to search and I do find a link to Yahoo Mail Sign In,but when I click on it,there appears so many google ads links and I still can not find what i'm looking for.I have tried to type yahoomail,mail,mail!yahoo,etc.They are the same too. Have I typed wrong?It should be very easy to search website,then what's the reason?
