On March 1 this year Google will share your Google history with the rest of 
the "Google world".

You can see what Google has recorded of your searches:

web-history/>

My question:

The ability to see and remove your Google search history applies only if:

1. you have a Google account , and

2. you are logged in when searching

yes?

In other words, does Google log search data by IP address (if you don't have 
an account), and is it possible to see and remove such if you don't have a 
Google account to log in to?

Thanks.
