The Google advanced search page has been updated with a new design, and the new page has certain old search options removed. Now on the new Advanced Search page, you cannot search for pages similar to a page, nor can you find pages that link to that particular page.
The 'Link To Page' was usually reported to be faulty and it comes as no surprise that Google has removed it. However, you can search for links to a page by “link:www.example.com” , but no guarantees for accurate results.
The other features of Advanced Search have been left as they were.
