When you type a term into the search box, you may notice that Discovery will provide you with suggested search terms. These suggested search terms can be helpful in expanding your search to include other relevant terms.
Example: If you type the words "Spanish flu" into the search box, Discovery will suggest the terms below. These additional terms may include helpful variations that will bring back a larger number of results AND more relevant results than the single term you entered.
