Google in progress to show a new universal search result with related queries. If you search for the name of a category, Google will list some of the most popular members of that category. For example, you can search for [German cars], [rock bands], [Indian food], [nuts], [clouds] and Google will show a list of items from that group. Google says that they are the top references for that question and it will also list three sources, without linking to the appropriate pages.
The feature is powered by Google Squared and it's not very new. Most of the results were available if you chosen "related searches" from the search options sidebar.
"Sometimes when you're searching, you're not just looking for one exact result, you may be looking for a list to start a series of searches. For example, if you search for [greek philosophers], many search results talk about well known philosophers like Plato or Aristotle. Typically, searches like these are the start of a research task, where you follow up by probing to learn more about each item in the list, in this case each philosopher," explains Google.
Just like the connected searches box, the "top references" box lets you try different queries without having to go back to the preceding page. If you click one of the connected searches, the box is moved at the top of the page and you can quickly sample the results for all the other items.
Google also in progress to show relevant lists for actors, movies, TV shows, music artists, writers, painters. For example, when you search for [Picasso], Google shows a list of famous Picasso paintings and small thumbnails. Searching for a movie or a TV shows brings a list of actors, searching for a singer shows a list of albums, while typing the name of a writer proceeds a list of popular books.
Google Squared, Google Q&A, "best guess" results and linked searches are just the tip of the iceberg. Google uses its huge index of pages from the Web to take out information, find facts and correlations, create lists and hierarchies, understand the meaning of a query and produce complex answers. At the recent Inside Search event, Alan Eustace said that his title distorted from "Senior VP of Search" to "Senior VP of Knowledge" because search is too limiting and Google's goals are much broader. They "go beyond the association of information to understanding and facilitating the formation of knowledge".
