Looking at the first five results from this query, there’s not much variety in
the returned DNS names. Only two unique domain names were returned—
www.microsoft.com and msdn.microsoft.com—the latter of which is most likely

“www.” One way to narrow our search to return more domain names is by
adding a negative search for www.microsoft.com. For example, consider the
results of the query site:microsoft.com –site:www.microsoft.com,or
site:microsoft.com –site:www.microsoft.com as shown in Figure 5.2.
This search returns more variety, returning four new domain names in the
first four results. ...
