Google has been testing a simplified new interface in Australia for Advanced Search. I haven’t seen any mentions of it from people in North America or elsewhere.
The top of the form seems friendlier:
Find web pages that have…
all these words:
this exact wording or phrase:
one or more of these words:
But don’t show pages that have…
any of these unwanted words:
Need more tools?
Results per page:
Language:
File type:
Search within a site or domain:
Then a collapsible area for “Date, usage rights, numeric range and more”.
It is currently visible at 72.14.253.104, 72.14.253.99, 72.14.253.103, and 72.14.253.147. This has only been seen for google.com, not google.com.au. I think Google has made the right call for me at least, as I rarely use the options that have been collapsed.
