Website Refinements allow you to search more accurately. For example, if your search is about art, you might want to search the "Art" collection. There are many collections to choose from. Click the collections drop-down to scroll and/or search available refinements to find just the right collection for your search. To search the entire web, don't select a collection (leave this blank.)
What are Top Facts?
Top Facts are usually found in databases rather than on the web. Searching facts can often help you find better search results on the web. You can quickly enter information into your web search by clicking the buttons at the bottom of each fact. Searching the words in these buttons can be very useful for constructing a search that will find the information you are looking for.
