Do you go to google.com when you have nothing to search for?

When you do, does the current opening UI feel that inadequate?

There's a simple reason they haven't added tons of UI elements for things like advanced search operators: the vast majority of the queries and the vast majority of users simply don't need them to get what they want from the tool.

FWIW, they have no reliable way of measuring what "vast majority of users" "want from the tool", or when they get it. Users navigating to one of the search results and abandoning the search may mean they found what they want - or it may just mean they gave up.
