A basic search is just that, a basic search. You can enter keywords such as a name, subject, publisher, etc. You can use the Boolean Operators (AND, OR, NOT) to search in the basic search as well.
From here you can also click on Advanced Search for a more specific search and you can view previous Search History.

If your search failed and there were no results, try using less words if you are using to many. Sometimes searching for phrases or sentences won't work.
If you are still receiving no results, try using different words or using Boolean Operators.
You can always do an Advanced Search if there are still no results for your search.
