This is a false statement. All advanced search features in Google Search are not included in other searches (in Youtube, Google Images, etc.). These options are only available in Google Search. Google Search is made up of a variety of regional websites. The most famous of these, google.com, is the world’s most visited website. It contains a definition link for most searches, including dictionary terms, the number of results you obtained on your web, links to other searches (for example, for words that Google claims are misspelt, it offers a link to the search results using its suggested spelling), and many other features.
