In each search box you can type the words or phrases you want to search for. Within each box search operators can be used to enhance your search and to combine search words and phrases. Multiple boxes are combined with the AND Boolean operation.
Each box has a drop-down next to it that lets you specify the type of data you are searching for (author, title, subject, etc.). You can mix and match search types however you want.
